People are expensive but few. If you can't talk, you can find a "secretary" who can talk. She said you kill two birds with one stone by taking care of your hair! If you can't, it's simple: according to the occasion where you want to send a red envelope, if it's a farewell party, say thank you so-and-so and come to our wedding. I hope everyone can share this wonderful day with you with a small gift package. It's easy to recite a few more idioms: when there are many people, it won't be very abrupt to give red envelopes one by one!
