The opening words of Youku Yanhuang's tomb-robbing history are the top four in history, what is behind?

There are four major schools of grave robbing in history: touching gold, unloading mountains, climbing mountains and moving mountains. Among them, Mojin is the sect with the highest technical content and the most rules. People light candles and ghosts blow lights, which is the secret of the legendary touch of gold. It means to enter the ancient tomb, first light a candle in the southeast corner, and then open the coffin. If the candle goes out, you must leave quickly and don't take anything. According to legend, ancestors made a contract between the living and the dead. Thousands of years of inheritance must not be broken.
