Zhang Xueliang's brother-in-law Bao Yinglin. Bao Yinglin, a native of Fengtian Haicheng, and Zhang Xueliang were born and raised. He is the son of Bao Guiqing, governor of Heilongjiang Province. At the same time, he and his brothers Bao Yulin and Bao entered the first phase of Northeast Club to study cavalry. He is also Zhang's brother-in-law, her husband, Zhang's eldest daughter and Zhang Xueliang's brother-in-law. It is said that the marriage of Zhang Xueliang's younger sister Zhang Shoufang and Bao Yinglin is a victim of political marriage, because they obviously don't love each other, but the wishful thinking of their elders is the only way to consolidate their sphere of influence. After Zhang's death, Bao Yinglin filed for divorce and remarried. However, influenced by traditional ideas, Zhang Shoufang did not agree to divorce. But in the end, Bao Yinglin married someone else, and Zhang Shoufang was unhappy all his life. After the September 18th Incident, Zhang Shoufang followed Zhang Xueliang around until the Xi Incident when Zhang Xueliang was imprisoned. Life was once very difficult because there was no source of income. After Premier Zhou knew about it, he specially transferred a house and subsidized it regularly, so that he could spend his old age safely. However, Zhang Shoufang and Bao Yinglin had three daughters and two sons, and Zhang Shoufang died in 1954.
