How to be polite when sending a group message on WeChat?

You can address your boss, peers you often deal with, or you can address them humorously: dear friends.

Please look around immediately after receiving this message. Have you found the person you are looking for everywhere? Like you, he looks around with his mobile phone. If so, please give him my regards. If he says hello to you, he must have received the same message as you. If not, then the only person I want to bless is you. I wish you happiness. "
