Why did China adopt the AD calendar?

The reasons why China adopted the AD chronology method are as follows:

1. Chaos in the old days: There are many ways to date the chaos in the old days, such as Kangxi and Qianlong. This led to all kinds of confusion, even the newspapers at that time didn't know how to write.

2. Connecting with the world: 1949 On September 27th, after the first plenary session of China People's Political Consultative Conference, the newly established People's Republic of China (PRC) adopted the Gregorian calendar and the calendar commonly used by most countries in the international community.

In a word, China adopted the method of AD chronology mainly to solve the chaotic problems in the old days and connect with the world.
