Customs of Mid-Autumn Festival:

On Mid-Autumn Festival, southerners will put lights in the river to commemorate their dead relatives. Northerners often hang lanterns and burn incense in front of their relatives' graves to commemorate the dead.

In fact, in ancient times, lanterns were hung on the Mid-Autumn Festival to enable those ghosts to support themselves and no longer suffer from eighteen layers of hell. In the true meaning of Buddhism and Taoism, it can also be called "filial piety festival". Therefore, the Mid-Autumn Festival is a festival of double filial piety, which can not only mourn the dead, but also remind people of their parents' kindness.

On Halloween, adults and children will make some lanterns, light candles, write some blessing words on the paper wall of lanterns, and then go to the river to set off lanterns together.
