There were two different summit plans, one for Zhang (she planned to break the speed climbing record without O2), another for other 2 climbers. Zhang left BC at 1:35 am on 24-Sep and slept C3 overnight. In next day, when she touched near 8100m on planned summit day and noticed that her four fingers had turned into black. After some Sherpas' suggestions she decided to descend immediately because she thought it may cause frostbite. After she reached C3 and met other team members, Sirdar Nurbu Sherpa told her it because of color faded on her gloves. Anyway she decided to give up and went back to BC in the same day on 26-Sep.

Other two climbers Hu and Li left BC and slept at C1 on 25-Sep, then slept at C2 on 26-Sep. Both of them started summit push from C3 at 6-7 pm on 26-Sep, summitted between 3:30-6:30 am on 27-Sep. Hu waited for sunrise to take summit photo from 4 am-6:30 am near the top. Li Kai reached BC in the same day. Hu Hong-Zhi stayed in C2 overnight and reached BC in the next day on 28-Sep.
