atmospheres:
The ones I was most interested in was a rumored wuxia with him and Zhang Ruoyun, and a wuxia with him and Cheng Yi (Zhang Wanyi's name was also mentioned as possibly involved with one of those but I don't remember which one),
I've heard of the one with Cheng Yi, it's rumoured to be a wuxia, right? If it's in the vein of the Mysterious Lotus Case book, it would be good. I don't think TJC has ever been in a wuxia before. Zhang Ruoyun is a solid actor and will give TJC plenty to play off, that would be an interesting pairing.
The one rumoured with Zhao Lusi is, I believe, from the same team that did Love Like the Galaxy. I enjoyed that drama and it was very well received. What I hope is that it won't be a story that focuses on the female lead, while the male lead is in a more supporting role. Love Like the Galaxy was co-lead, both female and male leads had their arc and development. I think to get to the next level, TJC needs to successfully carry a drama where he is clearly the lead protagonist.
atmospheres:
And there's Si Ming which seems like it might happen but I can't say that I'm excited for it because while I don't dislike Li Yitong, I don't find her interesting to watch she's a serviceable actress in my mind but that's about it.
I agree that Li YiTong is serviceable, but un-exciting. She reminds me of Li Qin. Both are serviceable but lack a certain screen presence and audience affinity. I don't hate, but I don't love.
Did you see the rumour about the project with Deng Wei? That one doesn't look too credible and I hope it's not true since Deng Wei is really not a good actor at the moment.
