How can my son reply to the message when he sends a red envelope?

When a son sends a red envelope, he can reply to the text message like this:

1, I received your red envelope, thank you very much! I feel very happy to have you as a dutiful son. May your life be full of joy and happiness.

2. Thank you for the red envelope from your son. My mother feels very happy. Son, you know your heart, and your mother will always remember it. I wish you all the best and happiness and health forever.

Dear child, I really appreciate you giving me this red envelope. This is my favorite gift, and I received your kindness. I will use this red envelope to buy what I need. Thank you, you are such a lovely child!
