In fact, Chen Zhan's senior NT career ... After the Finals of 2014 WCH, Chen Zhan has become the fourth libero. She finished her NT career in 2016 WGP (in theory, she could participate in 2017 Montreux but Fujian and Shandong were both Top 8 of Chinese National Games 2017, therefore, still Lin Li and Wang Meng-jie) and her club career in Chinese League 17/18 with Hui Ruo-qi and Jiang Qian-wen.
