Later, someone in the family building heard the battalion commander's mother say that Lu Xingzhi had left that day. She also said that he did not know how the world worked. When Mrs Lin heard about that, she laughed about it with her husband.
The battalion commander's mother thought that her son should not do the dirty work of clearing a clogged toilet because he was a military officer. She was an old lady, and her daughter-in-law also did not know how to do it, so it was only fitting for her to look for Lu Xingzhi as he was her son's subordinate.
