------------------------------------
[~julianhyde] Thank you very much for telling me the importance of jira and
many good development habits and suggestions. I will update this jira according
to mihai's explanation. Then update it to jira according to the instructions in
the JoinConditionOrExpansionRule.java file. In addition, I would like to ask
for your advice. Can I modify the name in the current jira at the same time?
