Every time before opening the coffin, three sticks of incense must be placed in front of the coffin. Firstly, it is to show respect for the owner of the tomb, and secondly, it is to communicate with the tomb owner to see if the tomb owner welcomes you.
Although people are dead, their souls are still there. Don't think that you can do whatever you want in other people's homes after you die. This is a taboo.
Beautiful, wonderful, great
