The future is long, what a joy it is. Gu Zhi'an was very grateful to God for his arrangement that allowed him to meet his sister whom he had not seen for a long time in this strange city. Just like when he traveled to Beijing and his mother was suddenly admitted to the hospital, his wallet was stolen and he stood helpless at the hospital's payment desk, and then the god of fate favored him. Maybe he has always been lucky enough. He doesn't know what the future will be like, but it will definitely be like what was written in a book he read many years ago: When we meet again and again by chance coincidences of fate, and luck comes unexpectedly, all we need is to be content with the situation.
