Qi Ji always felt that Zhang Beihai had something hidden about Qin Shuhua, so he came to Zhang Beihai's house on his own initiative. Zhang Beihai asked Qi Ji to bring Zhang Chi a car diary.After reading the diary, Zhang Chi realized that when he was a child, he thought that his mother's departure was caused by the breakdown of the relationship between his parents. This was actually a big misunderstanding.
At that time, Zhang Beihai took more care of Chen Guizhi just out of kindness and a doctor's instinct. Zhang Beihai had no doubts about Qin Shuhua.At that time, Qin Shuhua was too obsessed with work and had high demands on himself. Over time, his mental state was worrying, and he eventually suffered from bipolar disorder, leading to suicide.
