The three astronauts from Shenzhou-20 are expected to return on Shenzhou-21.

PlanValue 3.0Nov 8, 2025RT by @insomniacai163: No update from China's human spaceflight agency on the possible debris impact on the Shenzhou-20 spacecraft. Insiders on weibo suggest a decision soon, which will be very much safety first. We could see Shenzhou-22 launching without crew, and the 3 SZ-20 astros returning on SZ-21

Shenzhou-23 will be prepared in the background as an emergency backup for Shenzhou-21 crew.

PlanValue 3.2Nov 8, 2025R to @AJ_FI: Things to look for include activity at Jiuquan, such as rollout of Shenzhou-22, which is already in state of near-readiness, while SZ-23 will also need to be prepared in the background for an emergency to cover SZ-21 crew. Tiangong should be able to host the 6 astros for a while.
