1. Thank you for your kindness. I have received your kindness and don't want the red envelope.
2. When you are so big, you don't need to give any more red envelopes. Keep the money and buy something for yourself. I appreciate your kindness, and you must understand my heart!
3. I won't accept it. I have enough pocket money, and I feel the love of my relatives. Don't give me a red envelope.
4. I am too old to take this red envelope.
5. I have grown up, so I don't accept red envelopes. Thank you for XXX's red envelopes.
6. I have grown up. I'm sorry you gave it to me like this. I dare not come next time.
7. I originally wanted to give you red envelopes, but then I remembered what Chairman Mao said: "Holiday greetings are not the monopoly of the bourgeoisie. We proletariat should also greet you, even if we are not afraid of greeting late. Nothing more than bowing your hand and saying something auspicious.
