This is the continued story from my Dad:

“At the beginning, the letters that we sent together were frequent but became gradually scarce after some time: each of us occupied ourselves with work. But one day, he appeared suddenly in front of the door of my bureau, with him there was a slender girl, his fiancé without any doubt. They stayed with me only one hour and returned afterwards to Tianjin.
Some days later, I received a letter from him, in which he told me he would like to introduce a girl to me, who was a professional singer, was working for the army in his city. I refused; thinking any one who didn’t live in Beijing was unacceptable for me. He was very disappointed and wrote me a letter to express his feeling; I shook my head in a smile: I didn’t care about.”

That is good that my Dad did not do anything, otherwise, he will never get to meet my mom, which was his soul mate for years, (she passed away 6 years away). So my Dad make a great decision at time, this is the first time I heard this story from him.
