ILUVMONEY

He doesn't do much OSTs, but this one gave me such a sad feeling:

He's been doing a lot of musical variety shows lately, so you can check that on youtube.

A-lin, and Yuan Yawei are also really good but they also seldom do OSTs, but I consider these singers I've mentioned as heavyweights.

They're all sad ballads, but I hope you enjoy it!

I'd highly recommend Jane Zhang, Yu Kewei, and Terry Lin.

Nirvana in fire is great if you like strategic scheme to unveil a mysterious event. Longest day in Chang'an is suspense with amazing settings and costumes. Untamed is fantasy with ghost spirits. The rebel is a republican drama with spies and moles.

I watched the first episode but man...there's a lot of good looking guys in this show, and I'm not gay!

Thank you! Bummer...no English subtitles.

Where can I watch this Turkish series?

Your welcome!

If I'm not mistaken, both were speaking Sichuan dialect (China's Southwest).
