The main reason is that the influx of ancient refugees is often accompanied by natural disasters or man-made disasters, which are popularly known as droughts and floods and wars. In this case, everyone can't take care of themselves, and there is no extra money and food for others.

Entering the wasteland is an unruly place. When there are natural and man-made disasters, people often take advantage of the fire to rob, so ordinary people live in dire straits for fear of being caught by robbers, and refugees often pose a serious threat to social security.

Moreover, under the rule of feudal ethics in ancient times, the ideology was rigid and hierarchical, so the tramps at the bottom rarely had access to the dignitaries at the top, and the wealthy businessmen thought highly of themselves and could not get a lot of charity. The street beggars seen in the TV series are just plots specially designed to set off the atmosphere.

Although it is difficult to get rich, it is not impossible to seize the opportunity to worship the king, such as Zhu Yuanzhang, the founding emperor of the Ming Dynasty.

The ugly Zhu Yuanzhang had a bad childhood. He finally settled down in the temple, but never thought that he had encountered another drought and went out to beg for a living in the name of traveling around the world.

Enriching our horizons all the way coincided with the heavy taxes in the Yuan Dynasty, which made the world complain, and the nobles did not regard the people as fish. So Zhu Yuanzhang took the opportunity to put forward his own ideas and slogans, gathered a group of poor Han Chinese together, gradually formed his own power, and finally successfully overthrew the rule of the Yuan Dynasty.

Throughout Zhu Yuanzhang's life, he is definitely a model of diaosi counterattack. But his success is not accidental, but the result of favorable weather, favorable geographical position, people and complementarity.
