How to inform a friend of a funeral at home?

According to rural regulations, if a family member dies, the relevant person should be informed immediately. Generally, except for relatives and elders, the village should tell them face to face, and hanging a white door at home is equivalent to informing the whole village. For relatives and friends who are out of the village, we should use various tools to inform them. This step is called "sending a funeral" in funeral treatment;

Relatives and friends who saw and received the death will come to express their grief. This step is called "condolence"; Mourning at the moment of mourning can inform relatives and friends of the time when the deceased was buried.

Now, if you want to tell the burial time of the deceased by mobile phone information, it is very simple. I don't know how difficult it is to send this question.
