Why don’t others listen when I teach Buddhism to others?

The result of karma and immature timing.

First of all, how much do you know about Buddhism? Do you have a partial understanding or a systematic understanding? Whether what you have mastered is the righteous Dharma, whether there is any problem with the way of explanation, and whether the "true meaning of Tathagata" can be explained clearly. If you don't want to be "consummated" yourself, then don't tell others about it. Don't explain it with arrogance. If you don’t really understand and can’t explain clearly, how can others listen carefully?

Secondly, do others have interest in Buddhism and want to understand it? If others do not understand Buddhism and only have misunderstandings, it is not appropriate to tell them hastily at this time. Otherwise, it will only cause greater rejection and resistance on his part.

Again, it is a matter of timing and method. Buddhism is the Dharma of the mind. Only when the minds of the lecturer and the listener are in harmony, can the good effect of "heart to heart" be achieved. Therefore, when teaching Buddhism to others, you must first check whether the person is sincere in "seeking Dharma." If the other person treats Buddhism as superstition or a joke, can you still hope that they will listen?
