Is the poll tax a precursor to a dynasty change? It's purely a historical issue, don't be harmonious, thank you

No.

A poll tax (poll tax or head tax) is a tax that imposes the same, fixed amount on everyone (different from the percentage of income). In the 19th century, this tax was an important tax in many countries, but this is no longer the case. There are several famous examples of poll taxes in history. In some parts of the United States, poll taxes were used as voting qualifications; the main purpose was to exclude African Americans, Native Americans, and whites of non-British descent from the right to vote. The British John of Gaunt and Margaret Thatcher also imposed poll taxes in the 14th and 20th centuries respectively.

In ancient China, there were examples of the collection of poll taxes. During the reign of Emperor Kangxi, he once said, "Never add taxes to the population as it grows," and abolished the head tax on the regenerated population. During the reign of Emperor Yongzheng, the poll tax was officially abolished.

In modern China, a poll tax was also levied. Around 1999, some rural areas in China (such as Jinzhai, Anhui) once levied a head tax. Each person had to pay more than 200 yuan. Families that did not pay the full amount of this tax were unable to go through formalities such as studying and getting married. Since then, Taxes were eliminated.
