"Key To The Phoenix Heart" will be special. Ma Qiuyuan and Ai Mi acting in this drama are lauded for acting talents suitable to the respective roles. As I previously mentioned while answering another MDL user, "Kung Fu Soccer" should air in cinemas this month before "Key To The Phoenix Heart", since Global Times has covered this.
Given their Hong Kong movie backgrounds , Director Gao Yijun has fundamental signature similarities to Yuen Woo-ping, when it comes to filming battle scenes for historical dramas:
Live pyrotechnics and explosions, extended long-take sequences unless there is no choice (both directors despise green screens), equestrian training for different horseback battle or combat scenes happening across various landscape scenarios (Yuen Woo-ping likes deserts, Gao Yijun likes cliffs), etc
Equestrian training, wirework training, plus action training related to weaponry and/or martial arts are the basic requirements for anyone who wants to be selected by Yuen Woo-ping for a role in any of his movies. Director Gao is slightly more lenient on that front. But given how Gao Yijun exacts the best performances from a cast, I'd say his non-action emoting scenes are probably the equivalent of being put through the paces by Yuen Woo-ping after someone else has hammered home necessary basics.
Anyone ignorant of Gao Yijun's work will insult him, instead of praising him as I have.
Sun Mengfei would definitely be happy collaborating with Gao Yijun.
There's a lot of unhappy viewers wrt at least three not-aired historical costume dramas helmed by Director Gao. "Key To The Phoenix Heart" gives me hope that one other drama of his will air.
I am aware of spoilers (such as Peter Ho's role relative to Riley Wang's role and how that affects the plot) which could go under a spoiler tag, but I have chosen to keep those details out of this forum thread.
The pre-broadcast sponsorship drive for "Key To The Phoenix Heart" was recently launched on 2 July.
Yesterday on 3 July, samplers for the official drama OST of 6 songs featuring established powerhouse vocalists and rising talents was released. Huang Xiaoyun, Liu Yuxin, Duan Aojuan, and Jing Long contribute their talents, to sing of bonds forged amidst this era of uncertainty. Key theme song "Blazing Light" is a hugely-anticipated duet between Hou Minghao and Zhang Bichen, where deep affection amidst turbulent times underlines the voice of destiny soaring above the chaos of the battlefield.
Hou Minghao also sings the drama's opening song (which you'll find online in English under unofficial names of "A Promise Becomes A River" or "A Promise Flowing Endlessly Like A River" depending on whoever is translating the title), about family and country and a warrior's vow to protect what matters with all of himself. "A Promise Boundless As A River" is my take. All very poetic!
A-List Powerhouse singers are Huang Xiaoyun, Zhang Bichen and Liu Yuxin.
Duan Aojuan and Jing Long are rising stars.
Huang Xiaoyun is noted for her exceptional vocal prowess and whistle register, specifically her 'dolphin voice' technique and an exceptional coloratura soprano range.
Duan Aojuan has clear pure vocals.
Jing Long adds a lower range and provides added variety alongside the rest of the vocalists.
Zhang Bichen is lauded for her masterful performances for OSTs.
Netizens and industry commentators alike lauded Hou Minghao for his "solid vocal technique and exceptional ability to convey emotion", while fans lauded the Opening Song as "electrifying" and "awe-inspiring" while conveying an intense sense of destiny.
On Weibo, the OST is being praised by netizens for being incredibly immersive.
《知我》by Liu Yuxin is the only title I won't translate because "Know Me" doesn't capture the classic literary references of those two words, such as “知我者，谓我心忧；不知我者，谓我何求。” and/or alluding to the concept of a soulmate (in the sense of someone who truly understands you and your heart, and a trusted confidant).

Wow! I'm speechless. Thank you so very much for this wonderful and comprehensive write-up. This is the straight facts and career deep dive post I always wanted to make in defence of Ai Mi's inclusion in KTTPH and her overall recent step up to lead roles, but never truly had the ability to articulate. This covers absolutely everything. It's been so frustrating seeing her take a pounding this year with accusations flying at her from every direction. She's endured a lot. Fingers crossed she receives the exam results she's after and can enter the BFA full of confidence. It was such a rotten thing to put her on the spot during her examination period. I really hope it didn't rattle her. I simply can't wait for this drama to air next month 🤞🤞. I believe it will be special.

Now I am even more interested in this. I hope there is some romance.
I have done a deeper dive into the details of "Key To The Phoenix Heart", pertaining to C-Ent comments of novel versus original script. A year ago in July 2025, I started this forum thread, but had not yet included this detail about KTTPH as original script or novel. More than ten months ago in August 2025, someone on the KTTPH drama page claimed KTTPH was an original script. Despite having checked all details available for my July 2025 forum post, I didn't do my usual due diligence of fact-checking this claim, hence one of my later replies on this forum thread echoed this mistake.
"Key To The Phoenix Heart" is an adaptation of the historical novel of the same name 《雀骨》by popular web novelist Chao Yunzi, who also wrote the novel 《云初令》adapted as a drama (and now known as "Yunchu's Vengeance" on MDL, which has not yet aired and I have incorporated describing as part of an article for MDL) ->
https://news.mydramalist.com/article/revenge-retribution-responsibility-in-upcoming-zhang-yun-long-dramas-with-ju-jing-yi-esther-yu).
Due to major significant innovations during the adaptation process, many viewers (mandarin-speaking domestic, as well as international) mistakenly believe"Key To The Phoenix Heart" is an original screenplay.
1. Official confirmation of adaptation from the novel of the same name
Information from multiple authoritative media outlets and streaming platforms confirms that 《雀骨》(also understood as Sparrow Bone) is adapted from the novel of the same name by Chao Yunzi. Official promotional materials from iQIYI plus official production filing records all explicitly state that the series is "adapted from the novel of the same name by Chao Yunzi". The original novel is a historical romance centered on political intrigue, featuring a "dual-protagonist powerhouse" dynamic and a "marriage-first, love-later" storyline, revolving around the fated entanglement between Xiao Wuyi—the Heir to the Prince of Jing'an—and Xie Jiayu, the daughter of the Grand Tutor.
2. Retention of Core Elements from the Original Work
The TV adaptation "Key To The Phoenix Heart" faithfully translates key elements of the source material—such as the "marriage-first, love-later" dynamic, the parallel growth of two powerful protagonists, a political marriage, and a plot involving the falsification of weaponry—onto the screen. Key character traits and narrative arcs—including the male lead Xiao Wuyi’s outward persona as a violent dissolute womaniser masking the secret burden of a false accusation of regicide, and the female lead Xie Jiayu’s transformation from a political pawn into a rebel leader through her mastery of Mohist mechanics—are all derived directly from the original work.
Why has such a misunderstanding occurred?
3. Three primary reasons are likely:
First -> The adaptation involved significant changes, with screenwriters extensively restructuring the source material and adding numerous plot twists and original storylines.
Second -> Official promotional efforts highlighted selling points such as "power dynamics between two strong leads" and a "marriage-first, love-later" romance, leading viewers to assume the story was original.
Third -> the original novel is relatively niche; most viewers were unfamiliar with it and simply assumed the show was an original work based on their viewing experience.
A small number of users have noted "fans of the original novel say the adaptation didn't mess things up and that core character traits and plotlines were preserved" -> this fact itself confirms the existence of the original novel and indicates that the adaptation has won the approval of some of its fans.
"Key To The Phoenix Heart" is an adaptation rather than an original work, yet highly innovative.
It is a screen adaptation involving extensive reworking of the source novel. While the core plot, key character profiles, and pivotal conflicts are derived from Chao Yunzi’s novel of the same name, the screenwriting team contributed significant original work regarding narrative pacing, plot twists, and the fleshing-out of details. This distinguishes the final production from typical adaptations of established intellectual properties, leading many viewers to mistakenly believe it is an original story.
Do I need to read the novel, to enjoy "Key To The Phoenix Heart"?
No. Since the TV adaptation differs significantly from the source material and incorporates numerous original plotlines, viewers unfamiliar with the original work can dive straight into the series without worrying about spoilers or comprehension issues. Not knowing the story's trajectory allows viewers to experience a purer sense of suspense and greater enjoyment, while watching.
Viewers familiar with the original work will find the adaptation has been altered without being haphazard: Core character relationships and the main narrative arc involving power struggles remain intact, while the sequence of specific events, the fates of supporting characters, and key plot twists have been reimagined. Meanwhile, general viewers become fully immersed in the tight, fast-paced narrative. Unaware of the "traces of adaptation", they may even perceive the story as an entirely original work.
At a time when IP adaptations are frequently criticized for "drastic distortion" and "bloated pacing," Key To The Phoenix Heart—which deeply respects the spirit of the source material while boldly restructuring the narrative—has achieved a reputation rivaling that of truly original works. Abruptly moving up its release date with less than 48 hours of airing and reaching more than 1.5 million reservations before airing, then launching without any prior publicity? KTTPH popularity index on iQiyi rapidly surpassed 8,500 within 48 hours, making "Key To The Phoenix Heart" the potential dark horse summer hit drama series.

Conclusion
The success of "Key To The Phoenix Heart" is largely driven by a sense of originality that keeps viewers guessing about the plot.
"Key To The Phoenix Heart" is based on the novel of the same name by author Chao Yunzi; the plot is not entirely original but rather an adaptation. However, the extensive nature of changes made in the adaptation and its highly-innovative storytelling led many viewers to mistakenly believe it is an original screenplay. This phenomenon—where an adaptation feels as fresh and compelling as an original work—demonstrates the creative prowess of the screenwriting team and reflects the audience's strong desire for high-quality, unconventional, and bespoke dramas.
For the average viewer, there is no need to get hung up on whether the story is "original".
You can simply enjoy the tight pacing, plot twists, and the dynamic tension between two equally-formidable protagonists 😃😃
