When the provincial government sent a letter of appointment to Wu, the letter of appointment had been burned by Shen Biyun, and Xuan Zeen asked his family to investigate the letter of appointment that disappeared without reason. Shen Biyun suddenly admitted to burning the letter of appointment, and Xuan's family was shocked by her behavior. In the questioning eyes of everyone, she lost no time in explaining the reason for burning the letter of appointment.
The provincial government is ruled by Kuomintang warlords, and newspapers often publish news that warlords kill people without blinking an eye. If Wu goes to the provincial government with a letter of appointment, he will certainly go along with the warlords and rulers in the future.
