Since the solar calendar has been widely used, why hasn't the less used lunar calendar been abolished?

It is impossible to abolish the lunar calendar, not to mention that many festivals in China are related to the lunar calendar, such as August 15th and New Year's Eve. Even many older people have been counting days according to the lunar calendar in their minds, but it was suddenly abolished, which had a great influence.

Many young people think that the lunar calendar is changing all the time, and it is different every year, while the solar calendar is relatively stable, so why use the lunar calendar? That's because we are now based on the solar calendar, so the lunar calendar seems to be constantly changing. If we are based on the lunar calendar, it will be the opposite.

Moreover, the lunar calendar is a traditional calendar in China, which is much longer than the Gregorian calendar. The Gregorian calendar is only a manifestation of people's gradual westernization after the overthrow of the Qing government. This is how everyone calculates the years and months in a unified way. If the lunar calendar is really bad, it should be abolished when the solar calendar is first used.

I don't know if you have noticed that our lunar calendar is related to many solar terms, but the solar calendar is not so obvious. For farming, the lunar calendar also gives a lot of reference, and the solar calendar can't even clearly correspond to the seasons. The lunar calendar essentially combines the elements of the moon and the sun to consider the cycle, while the solar calendar only considers the sun, so the lunar calendar is much more accurate than the solar calendar.

Not to mention that the lunar calendar can't be abolished scientifically. In people's minds, the lunar calendar is deeply rooted. The concept passed down from generation to generation can't be changed for a while, but with an extra line under the calendar, everyone's habits can be followed. Why do we have to abolish the lunar calendar? Although the lunar calendar does not belong to one of the four great inventions, it also embodies the wisdom of the ancients. Why abandon fine traditions?
