Those contents in Morning Flowers and Evening Flowers describe the local customs of my hometown.

China has a tradition of attaching importance to customs since ancient times. "To be a politician, you must first learn the customs" and "observe the customs and know the gains and losses" are the ancestral teachings adhered to by emperors in past dynasties. The supreme ruler should not only personally ask about the customs and people's feelings, but also appoint officials to inspect the customs and people's feelings as an important reference when formulating national policies, so that historians will go down in history and leave experience in managing customs for future generations.

Custom is a behavior pattern or norm that people in the past dynasties followed in a specific social and cultural field. The diversity of customs is that people often refer to the differences in behavior norms caused by different natural conditions as "wind"; The differences in behavior rules caused by social and cultural differences are called "vulgarity".

The so-called "different winds in a hundred miles, different customs in a thousand miles" appropriately reflects the characteristics of different customs in various places. Custom is a social tradition. Some popular fashions, customs and inappropriate parts of the original customs will change with the changes of historical conditions. That's what the so-called "changing customs" means.
