What does it mean to light a red candle at the door of moving?

It is a custom to light red candles at the door of moving. In our country, red symbolizes happiness and auspiciousness, so many things should be red when moving. Some people with religious beliefs will light red candles and incense in front of the six gods of the land at home to worship Buddha, but now many young people don't care about this and it is unnecessary. The point is to be safe when lighting candles. If there are many children at home that day, be careful that children are near open flames.
