What song did Fan Wei dance in Big Ears of Blessing?

Blessed are the ears. Plot introduction:

In the winter in the northeast, a small town is as cold as ever, and people are as busy as ever, but today is a special day for Wang Daer, because he retired today ... After his retirement as a sophomore, Wang Ben enjoyed welfare benefits such as medical insurance in addition to his monthly pension of several hundred yuan, which Wang Ben should be satisfied with, but he always felt that he had no bottom. He thinks that no matter how good the unit gives you, you have to do something with your own hands. So I got up and invited the children to have dinner at night. I want to discuss my retirement plan with my children, so I got up early and went to the morning market to buy some things that girls and sons love to eat, and prepared everything for the dinner in the evening. Wang wanted to call some friends, picked up the phone and put it down, because his daughter-in-law was still lying in the hospital. Thinking of this, he remembered that it was time to send food to his wife. Before designing his first day of retirement, he rode his broken car to the hospital. My daughter-in-law has been in hospital for some time, and the doctor suggested observing for two days to avoid recurrence. Wang Ben wants to talk to his daughter-in-law about his plans after retirement. Looking at a group of patients in the hospital, he lost his mood and left without sitting for a while ... When he came out of the hospital, Wang rode an old car excitedly, strolled in the street, walked through the crowd and pondered his plan. So Wang began his first day of retirement. In order to realize his own ideas, Wang Daer visited the one-dollar shoeshine hall one after another on this day; A rickshaw puller riding a donkey; Two people turn friends in the small hall; The veteran cadres are taking a bath; A woman who shaves; The shopkeeper ... he told them his ideas, and most people didn't understand Wang Daer's ideas. Retired, well paid, why not enjoy your old age and do something. By chatting with these people, Wang Daer strengthened his idea of making a difference. He felt that he would not be complacent if he didn't do it. He found a survival chain, shoeshine to earn money to shave, shave to earn money to take a rickshaw, rickshaw to earn money to buy food, and sell vegetables to earn money to shine shoes ... After a day's investigation, Wang finally had a good idea for his future, that is, to open an auto repair shop. Wang's idea is simple, the purpose is not to make money, but to live in this guaranteed chain. He thinks I'm doing it for everyone and everyone is doing it for me. If shoeshine people earn money to shave, shave people earn money to ride rickshaws, rickshaw people earn money to repair cars, rickshaw people earn money to buy vegetables, and vegetable sellers earn money to shine shoes ... Wang Daer can't wait to talk to the children about this idea, and soon a table of dishes will be ready. When the girl and her son-in-law arrived, they began to feel awkward. Unfortunately, the son-in-law received a very ambiguous phone call on the table. Before Wang could discuss his ideas, the girl got into a fight with his son-in-law ... Wang was confident in his ideas, but he knew his daughter-in-law didn't want to listen to him talk about his life after retirement. So after dinner, I took a pot of my favorite flowers and gave them to an old friend as a gift. One is to tell my old friend what I think, and the other is to hope that this old friend can help. The old friend readily agreed to help, which made Wang very happy. Coming out of a friend's house, Wang turned and saw his father, who lived with his second son. The second daughter-in-law recruited a group of people to play mahjong, and her father was busy. Wang has an unspeakable taste. He wanted to talk to his second brother, but there was nothing he could do ... At this moment, Wang's pager rang ... Wang's partner asked him to dance. They danced. Wang told his partner about his idea of driving a garage, and the partner was very supportive. He also gave Wang an idea to open one in front of the ballroom so that he could dance after repairing the car. Wang was very happy with the support of his partner. In the new song, Wang jumped wildly, as if no one else was around, as if he had forgotten all the unpleasant things ... At the end of the song, Wang rode his bike to send his partner home, and at this time, snowflakes floated in the sky again. Wang looked up at the snowflakes floating in the sky and whispered ... Wang Daer spent his first day of retirement.
