Who is Jerry Yan's good friend? Be comprehensive

Andy Lau (who became attached when filming, when Jerry sent a letter out of the album), Cai Kangyong (Jerry's close friend), Size S (always very good, although rumors and Big S are not good, but privately very good), Patty Hou (Jerry helped Pei Cen when he needed help very much, and Pei Cen mentioned Xu Xu in his book), Rainie Yang, Jolin Tsai, Chun Wu and Hou Wenyong. Hong Xiaoling (very iron, a friend when he was not famous), Cai Zhenxun, Chen, Fat Sister, Sammi Cheng (Sammi Cheng's best friend in Kangxi is Jerry's platform, haha, they are very similar in character).
