When a daughter gives birth to a son, she sends a text message to her in-laws.

* * (as you usually call them), hello! We are deeply gratified and happy to hear that * * (as you call your daughter) gave birth to a baby safely! At the same time, I would like to express my heartfelt congratulations to you! I also want to thank you for your careful care of * *, which is your hard work for today's good news! We will visit and congratulate you at an appropriate time, and the time is to be determined.
