I know, if you mentioned the novel 'Sand Sea' They didn't tell it. But we mentioned about the adaptation 'Tomb of the Sea'. Still, people who watch the adaptation called Zhang Rishan as the new leader of The Mystic Nine.

If you can tell, Zhang Rishan is a liutenant of Zhang Qishan. However Zhang Qiling is still their patriarch. After the dead of Zhang Qishan and his wife, Zhang Rishan is the new leader of The Mystic Nine. That's why he's appeared multiples time in the universe, especially Tomb Of The Sea.

Yes, so many. Because Zhang's Family are so big. There are 2 kinds of Zhang Family. The one related to Zhang Qiling, the other one related to Zhang Qishan

It's not related to the main story of PingXie character, but still including the Lost Tomb universe. Like a spin-off. The story is about the other members of Zhang Family

Because mostly, they shot the drama in the winter or spring season.
