Temples in Thailand are like crematoriums in China, and cremators can also store ashes.
A venue will be arranged for relatives and friends to mourn in the first six days. It seems that I can go at noon, but I usually go at night, kneeling in front of the coffin and burning incense to worship the dead. Then at 7 o'clock, the monk will recite the scriptures. Usually there are four monks at funerals and nine at weddings. When monks chant, their relatives and friends put their hands on their chests together. After about 15-30 minutes, after chanting, you can eat. Funerals in Thailand are nothing like funerals. There is no sadness, but drinking, playing cards and laughing. Some people who come to the funeral don't know the dead, such as me, but no one cares who you are. Everyone sat together, chatting, eating and drinking. Some people come every day for six days, so that the families of the deceased will not be disgusted, because this is actually to help him keep up the scene, and many people have face. If few people attend, it means that people are not welcome. Generally speaking, China people and Vietnamese people don't like drinking. Some funeral traditions of China people are gone, but Vietnamese people still have the tradition of Pima Dai Xiao.
The last day is cremation day. Some are sent directly to the cremator, and some rich people will make a grand ceremony. Like the ancient ceremony, a group of people marched from home to the temple around the coffin-carrying car (I don't know if they thought it was a float), and everyone had to put a paper flower in the cremation furnace before paying attention to cremation.
Generally, it will be fine if it is burned. But if a centenarian or a very old man dies of natural causes, he will have to invite another guest within 100 days.
You should wear black or white for funerals, and centenarians can wear red.
Thais sometimes give small gifts such as Buddha statues, and some people give red ropes tied to their wrists.
