Congratulation to the end of the story, 66!
I have some comments for you to consider:
1. As a considerate official, Song would expect his futurn so he may transfer some money abroad. When he heard that Haizao is pregnant, he should let her immigrant to Canada or somewhere. I know a lot of examples in real life.
2. The story seems to end in a hurry.
3. What happened to Song's wife? She did injury to Haizao, she should be in jail or something.
I want to thank 66 again for letting us read the wonderful story!
