In other words, you have to stand half a step forward in front of the kneeling mat, and then hold your left hand with your right hand. Holding the left hand with the right hand is to worship the fierce, which is generally used for funeral or fighting.

Then kneel down, which is a kind of worship.

Then kowtow three times, that is, three knocks.

Stand up and step back.

Then repeat the action until you kneel down three times and kowtow nine times. This is the ceremony of three worships and nine knocks.

However, three worships and nine knocks are big gifts, which are generally only used for important occasions, such as ancestor worship or saving lives.

Generally speaking, a funeral or even a teacher's visit is enough. There is no such thing as three visits and nine knocks, because it is not in the identity of the deceased.

Just like you offer a cup of tea to flatter a low-ranking person, this will not only have no good effect, but will make high-ranking leaders feel disgusted and kill.

According to superstition, it will make the ancestors of the deceased feel insulted and easily hurt their descendants.

Therefore, three worships and nine knocks cannot be used casually, and ancient emperors will not easily accept three worships and nine knocks.

Unless it is four generations of old people, that is, after the funeral of grandparents' parents.

After all, it has been blessed for three generations, and even if it dies, it is enough to be called an ancestor. Only in this way can young people pay homage to their ancestors at the funeral and thank them for their blessings.

Even if your parents are buried, don't visit them three times and knock them nine times, which may make your parents uneasy after their death.

Therefore, it is etiquette to worship and knock three times at a funeral.
