Xiao Li's milk order was stolen several times over the past six months. He pretended to be a surveillance camera and discovered that it was actually his neighbor Aunt Wang who was wearing a mask and doing the theft. In order to protect the milk, Xiao Li switched to cash on delivery, but his aunt complained and claimed for cutting off my food rations. At the mediation meeting, Xiao Li relied on the purchase order, surveillance video and the milkman's testimony to fight back, forcing the other party to apologize and compensate. Although he won in the end, Xiao Li was disappointed with his neighborhood and chose to move and start a new life.
