In chapter 3 of Dream of the Red Chamber, the dismissed official Jia Yucun learns that former officials may be reappointed. On the advice of a friend, he asks Lin Ruhai to approach Lin’s brother-in-law Jia Zheng in the capital. Lin Ruhai says that he has not yet repaid Jia Yucun’s kindness in teaching his daughter. “I have written a letter of recommendation and asked my brother-in-law to do everything to help.”
In the capital, Jia Yucun presents his card at the Jia mansion. Jia Zheng has read the letter and receives him at once. Because the request comes from his brother-in-law, he treats Jia Yucun with special favor. Jia Yucun is restored to office, and within two months he fills a vacancy at the prefecture of Yingtian in Jinling.
