When she got married, he generously provided 300,000 yuan for her dowry and bought her the three traditional gold wedding gifts.

With a lawyer's help, he untangled the financial disputes, while his sister's marriage also came to an end because of her lies. After weathering this family turmoil, Shen Zhongshan let go of the past in which he had misplaced his affection, cut his losses in time, and began a new life of his own.
