Knock twice or three times?

The most polite way to knock is to knock three times, once in a while, and then a few times. Knock on the door and wait for an answer. If you don't hear "come in", wait for 3 seconds before knocking at the door and raise your voice moderately.

If the door says push or pull, it's very simple. Just do as required. But there are some places that have not been reminded, so we must pay attention to them. At this time, the sliding door is much more polite than the sliding door, because both doors are pulled in their own direction and it is not easy to bump into others.

Correct knocking etiquette:

The most gentlemanly way to knock is to knock three times, once in a while, and then a few times. Knock at the door with a moderate loudness. If you knock too lightly, others will not hear you. If knocking at the door is too loud, it is impolite and will arouse others' disgust. When knocking at the door, never punch, kick or bang. If there are old people in the room, they will be frightened.

If the door is unlocked, you should knock first and get the owner's permission before you can enter. When you enter someone's office, you should also knock at the door first, indicating a kind of inquiry "May I come in" or a kind of notice "I am coming in".

Office knocking etiquette: In the workplace, as subordinates, we often ask for instructions and report our work to the leaders. Knock on the leader's door and be dignified. After knocking three times, you will see no response. Knock again later. If there is still no response, it means that the leader is absent and it's time to go.

If it happens that the door of the leader's house is open or unlocked, we still have to knock, and we must never rush in without permission. If the leader doesn't hear the knock at the door because he is working hard, we'd better wait at the door for a while and then knock at the door; Or wait until you lead or find yourself, and then report your work. This will leave a good impression on the leaders.
