Who is Luo Jialun's wife?

Luo Jialun married Miss Weizhen Zhang, the daughter of Mr. Zhang Juncheng, in Shanghai on 19 161month1day (at the age of 3 1 year), with Mr. Cai Yuanpei as witness. Weizhen Zhang graduated from the Department of Political Science of Hujiang University with a master's degree from the University of Michigan. Legend has it that when Luo Jialun was studying at Peking University, he tried to chase after the beauty of Peking University with a love letter full of literary feelings. At first, he was rejected because of his ugly appearance. Later, I was moved by his talent and finally agreed to marry him on the following conditions: First, I want to study abroad and get a foreign doctorate. Second, return to China as a university president after graduation. Third, husband and wife should not be openly parallel, but should keep a considerable distance. Luo Jialun agreed to please the beauty. This rumor is inconsistent with Weizhen Zhang's information. It may be that his affairs at Peking University were exaggerated and misrepresented, or it may be fabricated to highlight Luo Jialun's talent and beauty. Another legend is that Luo Jialun also wrote to President Cai Yuanpei asking for an engagement with Mr. Cai's daughter. Mr. Cai replied to a letter to the effect that: marriage matters are independent of men and women, and I have no right to arrange them. As my daughter is not old enough to get married, your requirements are too high. This incident was passed down as a joke in Peking University.
