What does it mean to make a tree hole?

Making a tree hole is to keep a secret for others.

Tree hole, a popular word on the Internet, refers to the platform that carries secrets and private affairs on the Internet. The word "tree hole" comes from the fairy tale "the emperor has donkey ears", which refers to a place where secrets can be told without fear of leaking out. Because the tree hole has no function of talking, it will never tell a secret. Making tree holes means keeping secrets for others and becoming an object to vent bad emotions.

"Let me be your tree hole" means "Come and talk to me". It is not easy to find a "tree hole" in real life. People don't confide secrets to others easily. A tree hole represents the intimate relationship between two people, because real tree holes don't tell secrets.

The reasons for the formation of tree holes are briefly described as follows:

A tree hole is a situation in which some ancient trees gradually form cavities or even cavities over the years due to moth-eaten or mechanical damage, but the trees can still survive. The cause of tree holes is generally moth-eaten or mechanical damage. Some tree holes are formed because of the work of some cave animals, who dig holes in soft trunks as their nests. Such as squirrels, bears, etc.

When some trees are old, their cores will naturally die and rot, and they cannot be regenerated, thus forming tree holes. There are also some strangled plants that will grow around other trees. In a certain period of time, they will kill the plants inside, make the inside of the molded tree (strangled plants) hollow, and also form tree holes.
