if you mean the URL is :https://hive.blog/hive-143316/@dappcoder/steem-python-beem-20200329-cn
Sorry! That's my mistake!
Because it's not convenient to visit steem / hive app or network after hive hardfork.
So I use the command line of beempy tool to publish this post as HIVE Edition , But I post with the markdown file of STEEM Edition by mistake.
I have fixed with my HIVE Edistion markdown file.
