The Relationship between Changyi and Yanmei

Neighbors Chang Yi and Yan Mei are from the TV series Migrant Workers. They are neighbors. Changyi and Yanmei live in the same village. Changyi married a fat daughter-in-law and didn't like it very much. Sometimes when I go to Yanmei's house, she can't help feeling disgusted with her wife when she sees that the considerate Yanmei is very different from her wife.
