1, the fifteenth day of the first month is the night of the Lantern Festival. When it is dark, people will send lanterns to their ancestors, just where they rest, so that they can feel the greetings and warmth from their relatives. Specifically, it is on the grave where you lost your loved one.

2. It's lucky to light the lanterns first when sending them on the Lantern Festival. People who send lanterns to graves must use their own matches when lighting them. If they borrow someone else's matches to light them, they think their ancestors can't see the light.

3. When lighting a lamp, you should say one thing: on the fifteenth day of the first month, send a lamp, send a gold lamp, send a silver lamp, and send an iron lamp.
