Four questions belong to both of the above groups (have "Shenzhou" in the question, and tagged shenzhou-11).
We generally don't make tags for specific missions, unless they are so notable as to produce a large number of questions. There's not much notable about the Shenzhou 11 mission. However, tags about spacecraft families are very useful. Should the shenzhou-11 tag be renamed shenzhou, thus broadening the use of the tag to include questions about the spacecraft family?
