Yao Meijuan specially downloaded a movie about sister-brother love and went to the convenience store. She used the excuse to watch the movie with her daughter, but in fact she was acting as a lobbyist for Lu Xiaobei.

Lu Xiaobei began to implement his plan. He first called the police multiple times to complain that the square dance team’s speakers were too loud and disturbing the residents. Then he spent his own money to purchase headsets, peanut oil, and dance shoes... He said that as long as Joining Yao Meijuan's dance team was all given free of charge. Those square dancing aunts who were greedy for petty gains could not withstand the temptation and "surrendered to the enemy and the country" and gathered around Yao Meijuan. Naturally, Yao Meijuan has not forgotten her mission. When she invited her daughter to visit her newly formed environmentally friendly dance team, she did not forget to speak up for Xiaobei. She said that as the saying goes, "Men can endure old age, women can endure life." Nowadays Social pressure is high, men generally have short life spans, and most of the old couples left are old ladies. Most of the old couples walking on the street have the old lady supporting the old man. Seeing her daughter lost in thought, Yao Meijuan knew that her words had an effect. When they came to the supermarket to buy vegetables, Yao Meijuan used the tender vegetables to impress her daughter again. Yao Lan realized that Lu Xiaobei must have gone to see her mother. She immediately called Lu Xiaobei and asked him to stay away from her, and threatened Yao Meijuan if If he interferes with her business any more, she will move out of the house. Yao Meijuan and Lu Xiaobei found an opportunity to meet in private. Yao Meijuan said that she could create opportunities for Xiaobei, but Xiaobei had to promise that she could mess around, but not forcefully.
