Martial Universe 武动乾坤 begins filming on Nov. 14 though it seems like gossips overshadowed the actual event. Nevertheless, Yang Yang, Crystal Zhang, Wu Chun and Ashton Chen were all smiles in the prayer ceremony held in Xiangshan and it looks like they're bringing home red envelopes (money) too, likely given to them as a sign of an auspicious beginning. It's a Chinese thing.
Yang Yang offered his prayers, then Wu Chun was up next after Crystal Zhang gestured for him to go first, then Crystal Zhang took her turn and finally Ashton Chen, each holding the incense with both hands and praying to the gods three times. I don't actually know why they do it the way they do but it's exactly what I was taught as well.
Yang Yang introduces his character as a hero who fights evil for the sake of good and that he is extremely happy to be part of a talented team and thankful for the role that was entrusted to him. Separately, Crystal Zhang admits that she really likes her character's spunky personality and unwavering attitude when it comes to love.
