In Auld Lang Syne, Liu Xing is Liu's son, and the Liu family loves this son very much. Liu He's parents are very good friends, and the two just happen to be neighbors, so Liu Xinghe has been good brothers since childhood. They used to go swimming together, and as a result, Liu Xing drowned in the river. Shen Hao was the only one who came back. Liu Xing's mother's second child was lost because of Shen Hao's mother. Since then, Liu Jiahe has changed from a good friend and neighbor to an enemy.
But this is an ulterior motive. Shen Hao only told Liu Yaohui that Liu Xing drowned in swimming, but he didn't say why Liu Xing had to go into the water because he couldn't swim. In fact, at that time, Shen Hao deliberately encouraged Liu Xing to swim in the reservoir, and Liu Xing's good friend Shen Hao would not intentionally hurt him. This was originally just a joke between boys, but I didn't expect Liu Xing really can't swim. Under the provocation of Shen Hao, Liu Xing felt embarrassed and dived into the water, which eventually led to the tragedy.
Later, Shen and Liu broke up, and Liu moved out of their hometown and lived far away. They also adopted a child named Liu Xing, but their life is still very difficult. Many years later, Shen Hao met Liu Xing and Liu Xing was adopted. He was a little flustered and didn't know the truth. Shen and Liu are reunited again. At this time, Shen told the truth of the year and let Liu know how his son died.
