How does the story in Happiness end?

Li Qiang and Chen Waer are walking on the road, admiring the young people taking wedding dresses. Recalling when they just got married, Chen Waer complained that Li Qiang cheated himself for half his life with a can ring. It's a good thing he's gone and won't be cheated by him again. Li Qiang took out the ring box and said that she wanted to spend the rest of her life keeping her previous promise to Chen Waer, and she would go wherever she went. Li Qiang got down on one knee and proposed to the kids again. Chen Waer shed tears.

The synopsis of the story in Happiness;

1978, Chen Waer, Wu, Li Qiang and Hu Meihua all walked into the college entrance examination room. However, when the results were announced, Chen Waer and Hu Meihua failed the list, Li Qiang was admitted to the accounting school, and Xu Weidong went to the military school. Then the gap between their life and work opened.

Li Qiang, who kept up with the times, got the first pot of gold in the market and finally married Chen Waer. However, Chen Waer was self-expanding and abandoned his wife and children. Chen Waer was repeatedly hit by life but persevered, and finally founded a well-known enterprise. Hu Meihua, who went to the United States, turned into a financier and returned to the financial street after many years.

Xu Weidong grew up to be an excellent officer in the harsh environment of guarding the border. Wu, who was loyal to his duties, was assigned to the district as a grassroots cadre after graduation. At the same starting line, when the gunfire rang, everyone chose different goals to run forward, and the turning point of fate brought everyone together from time to time. Looking at the arched streets of the old hutong, this is already the financial street of the world.
