Please press the doorbell icon where you paste the picture.

Stick it on the door frame or directly above the doorbell button. The doorbell icon should usually be posted on the door frame or directly above the doorbell button so that visitors or couriers can see and ring the doorbell. If the doorbell button is on the inside of the door frame, the doorbell icon should be posted on the inside of the door frame, otherwise it should be posted on the outside of the door frame. Generally speaking, the location of the doorbell icon should be clearly visible, and at the same time, it should be kept clean and tidy so that visitors or couriers can easily find the doorbell.
