Shang Jiuxi and He Jiuhua entered the seventh team at the beginning of 2018.

Shang Jiuxi and He Jiuhua were originally members of the fifth team, but were later transferred to the second team. Because Xie Jin and Li Hedong were adjusted to the second team due to work reasons. In this way, fewer members of the seventh team can travel to other places. So Shang Jiuxi and He Jiuhua were transferred to the seventh team. The two worked together for seven years. It's a pity to be separated.
