Wu, 76, said the old colleagues still meet from time to time and reminisce about their time at work.
Among the artistes who met last Saturday were still-active actors such as Pan Lingling, Jin Yinji and Wang Yuqing.
There were also familiar faces such as Xie, Tang Hu, Yang Libing, Hong Guorui, Zhang Jinhua and Jin Jugong.
Wu shared several videos of the gathering on Facebook, including those of former TV host Zhu Yongqing conducting a charades game on TV show titles.
Xie, 62, a five-time Best Actor winner at the Star Awards, was seen in one of the videos raising his five fingers and pointing to his right leg.
Those present quickly guessed that it was Five Foot Way, the 1987 drama starring the late Huang Wenyong, Wang, Huang Peiru and Ye Sumei.
Chen, 57, who said on social media that it was a lively gathering, told Shin Min Daily News that she chatted briefly with Xie. He has kept a low profile since he left show business and moved to Malaysia.
“I asked him what he was doing recently, and he said he was not doing much,” she told the Chinese-language newspaper. “I remember meeting him twice when I went mountain climbing in recent years, so I asked him if he still climbs mountains. He said ‘yes’.”
