You can send a pair of wedding combs. Comb has always had rich connotations in ancient China, which not only represents the unity of knots, but also implies lovesickness, happiness and contentment. In ancient times, if there was a secret love between men and women, they would send combs for private life to show their desire to grow old together. In the old days, before a woman got married, her family would comb her hair, and there was a saying that "one combs her hair to the end, two combs her white hair and Qi Mei combs her children and grandchildren" to express her family's good wishes for the smooth and safe life of her loved ones. You can also carve words on the comb. When my sister gets married, I will hold your hand and grow old with my son.
