Donnie Yen Chi Tan and Tang Wei earlier appeared on a Mainland site Sohu to discuss the Peter Chan Ho Sun directed WU XIA. Playing a couple with Lynn Xiong (Hung Doi Lam) and Tang Wei, how would he rate these two "wives"? He stated, "Hung Doi Lam is a little taller than Tang Wei, but Tang Wei's performance was more than a little better than Hung Doi Lam's." Yen Chi Tan said, Tang Wei very obviously was a very excellent actress. No matter whether they would have a chance to work on another action film, working with her on this film her concentration and professionalism were unforgettable for him.
In addition, Tang Wei while making WU had to wear wet clothing everyday. For continuity she had to wear it for 10 to 20 hours. Aside from acting, she also had to have endurance. Thus Chi Tan praised Tang Wei and looked forward to working with her on another action film with him as the action director.
