Ditan Park is very close to my home. Or rather, my home is very close to Ditan Park. Anyway, I can only think that this is fate. Ditan Park was located there more than 400 years before I was born, and ever since my grandmother brought my father to Beijing when she was young, she has always lived not far from it. She has moved several times in more than 50 years, but she has always moved around it, and the closer she has moved to it. I often feel that there is a sense of fate in this: as if this ancient garden was waiting for me, and it has been waiting there for more than 400 years through all the vicissitudes of life.
