If someone asks: Where did the lunar calendar and the solar calendar come from? Why are there no players No. 1, 2, Or 3 on the basketball team? Why are surgical gowns green? Why do maple leaves turn red in autumn? Why does the solar eclipse occur on the first day of the lunar month instead of the fifteenth? Why do we say buying "stuff" instead of "buying north and south"? Was Wu Zetian the first female emperor in Chinese history? If not, then who? Can you answer questions like these? Perhaps you have discovered that these are common sense questions and that there is culture in every word you say. This book has a wide range of contents, covering all aspects of culture such as literature and art, imperial examination education, government regulations, scientific and technological inventions, customs and etiquette, clothing, food and daily life, festivals, astronomical calendars, religious philosophy, sports and entertainment, medical care, architecture and gardens, archaeological relics, natural creatures, geographical landscapes, history and military, political economy and other aspects of culture. It is both a dictionary for knowledge storage and a leisure book for after-life.
