Why don't many people know about the 24 solar terms now?

Because the twenty-four solar terms belong to folk knowledge and are part of our ancient excellent traditional culture, but now many of us give up our traditional culture when learning western culture. Especially under the influence of the New Culture Movement and later people's anti-traditional cultural thoughts, people blindly abandoned traditional things, so many people didn't know traditional knowledge such as the twenty-four solar terms and the three-character classics.
