Send you a short message and say "Happy Mid-Autumn Festival".

Happy Mid-Autumn Festival to you, too.

If you talk about other topics, he suddenly replies to you, proving that he doesn't care about what he just said, and even hates it.

And when you talk about other topics, he will also answer the phone and reply that you have something to leave temporarily.

If he says goodbye to you at this time, it also proves that he doesn't want to chat with you, which is similar to the meaning of the sentence 1, but I suggest you use the sentence 1 better, after all, it will appear a bit "dignified".

Expand information and send it to friends and colleagues. Try to write down what you experienced together. Send it to the leader and write down what the other person did or helped you. The more specific the content, the better, and the more in line with the festive atmosphere.

For example:

Thank XX leaders for their concern and support. I remember one month when you taught me what to do seriously and patiently, which benefited me a lot and impressed me deeply. On the occasion of Mid-Autumn Festival, I wish you …

If you can write the details clearly and vividly, it will evoke the memories of the other party and make the other party feel that you really sent your blessings.
