What do you mean, handed down from generation to generation? Detailed explanation

Because kindling is hard to get, the ancients cherished kindling very much. The tribe sent a special guard to add firewood to the fire from time to time to prevent it from going out. In ancient times, lighting, heating and cooking all depended on burning wood. In ancient times, firewood was called "salary". When the wage is ignited, its own combustion is endless, but the previous firewood is burned out and the latter firewood is burned again, and the fire is endless. This is called "handed down from generation to generation". (See "Zhuangzi * Health Master") Of the four major civilizations of traditional culture in China, only the one that has been passed down from generation to generation has survived to this day. In traditional culture, we also attach great importance to "inheritance" and "learning from". For example, Taoism originated from Laozi and Zhuangzi, and Confucianism originated from Confucius. Taoism Quanzhen religion originated in Wang Zhongyang in the Song Dynasty. There was a national player named Wang in the Tang Dynasty. "Accumulated salary" means collecting firewood. Legend has it that once he stayed in the mountains. In the middle of the night, I heard the shopkeeper: an old woman and daughter-in-law were dictating and playing chess in the dark. The chess game is very delicate. Wang secretly wrote down the chess score, feeling much higher than his own level. In the morning, both mother-in-law and daughter-in-law disappeared, and Wang realized that they were immortals. This chess score was later called the immortal score. Later, candles were invented, and the continuation of this civilization is also called "crossing the street lamp". In the Song Dynasty, there was a Buddhist document called The Record of Passing Lights (by Shi Daoyuan). Monks who contributed to Buddhism died one after another, but their wisdom can be passed down from generation to generation.
