Of course, you can send away the Guanyin statue. If you decide not to worship Guanyin, the best way is to send it to a nearby temple and let the monks in the temple help you deal with it. If there is no temple to send it, you can also send the Guanyin statue to a nearby mountain. The higher the better. It is best to put it under a big tree or a stone wall and set it up with the protection of mountain gods and passing gods. If you want to continue to worship Guanyin statue, but want to change the location, you can send it to the living room, study or attic for storage, and don't press anything else on it to maintain our respect.
In the process of sending away the Guanyin statue, we must maintain respect and piety, and we must not have any disrespectful behavior or words. If conditions permit, you can tell Guanyin in advance that you can't continue to worship and pray for forgiveness from Guanyin Bodhisattva. At the same time, you can also consider wrapping it with red cloth (don't turn it upside down) to protect the Guanyin image from damage.
