A rhyming joke

Confucius went whoring and met a stone. Stone said: it is predestined friends to meet thousands of miles away, and 200 yuan is not expensive! Confucius said: Qian Shan always loves thousands of waters. How about fifty dollars? Shi said to him: If you want to pass Yumen Pass, you have to walk at least 130 Li! Confucius said: There are plenty of fish in the sea. Can we do it for eighty dollars? Stone is speechless! Confucius also said: The world has its own true feelings. Today I only brought 90 yuan! Shi was furious and roared: I blocked tomorrow with my youth, and losing a hundred is also treacherous! Confucius said with a smile: Lushui couples also have feelings. Can we lose another ten dollars? Shi sighed: Why do we meet? You say 90 is 90.
