Others send couplets, there is no need to send red envelopes. You can give back some fruits, blessings and other items to express your gratitude.
The purpose of sending Spring Festival couplets is to show the artistic charm of China's calligraphy and further publicize the traditional culture of China. Sending couplets can also wish others a happy New Year. The significance of sending Spring Festival couplets is to stick them at home, and to wish neighbors peace, new journey and new hope in the new year in a way that is close to reality and integrated into life.
