Zhang San, a dude, specializes in making friends and makes countless friends. He was very tired, so he asked an expert how to make friends. Experts told him, "People who aim high can make friends, people who bear the burden of humiliation can make friends, and people without knowledge and skills must not make friends." Zhang Sanjin keeps it in mind.

One day, Zhang San met a eloquent man who claimed to be the first fairy in the world and was determined to catch a living ghost for scientists to study. Zhang San was deeply admired, and thought that this man had this strange ambition and should not be missed, so he gave him money to catch ghosts and became brothers of the opposite sex.

Another day, Zhang San met a beggar in rags kneeling in the street begging. He thought that this man could stand such humiliation, maybe he was a strange man, so he gave the beggar 100 yuan to pass through his crotch to test his virtue. The beggar got into his crotch with money and looked innocent. Zhang Sanqin accepted it and worshipped it as his brother.

A few years later, the Zhang family ran out of wealth and had few friends left. Finally, he was down and out, living on the streets, bragging and begging for a living.
