How to worship the old man who just died

According to the form left over by the older generation, we must kneel down to incense the portrait of the old man (the number of guests depends on the host), and we must hold the lit incense in both hands, worship three times first, and then insert incense; If the owner gives five-color paper, light it and put it into the basin. When the paper is burning, it ends with three taps on the portrait.

Of course, it doesn't matter if the host doesn't pay attention to it.
