What is a children's calendar?

Originally known as "Shu Tong", Cantonese people think that "losing" is the same as "losing", so they take the opposite meaning and call it "Tong Sheng".

Tong sheng, to put it bluntly, is the old yellow calendar. Nowadays, most of Tong Sheng's publications come from Hong Kong, including daily Gregorian calendar, summer calendar dates, official expenditures, solar terms, taboos, festivals (mostly traditional festivals, some even unheard of), and sometimes solar and lunar eclipses. In addition, many children also introduced various fortune-telling methods at great length, including old enlightenment textbooks such as Sanzi Jing, Zengguang Xianwen and Ganzi Wen, and introduced the basic knowledge of astronomical calendar-of course, this can't be rigorous, or even telegraph code. In addition, there will be an "English-Chinese comparison" for children published in Hong Kong-marking common English words with Chinese homonyms. As many children's covers say, "everything".

Simply put, Tong Sheng can be regarded as an ancient concise astronomical almanac plus enlightenment reading.
