Gifts, also known as gifts, are things that people give to each other in order to express their blessings and wishes, or to show friendship. Its purpose is to please each other or express goodwill and respect. Gifts are also used to celebrate festivals or important days, such as roses for Valentine's Day or birthday presents. Gifts can also be immaterial. There is an ancient saying in China that "a goose feather is sent a thousand miles away, but the gift is light and affectionate", which shows that the value of a gift lies in the goodwill and intention of the giver, not in the value of the gift itself. Especially a symbol of love. Gifts are not provided by the "donee" to the "donor" in the form of demand, but are given by the "donor" to show his goodwill under the influence of non-external forces, so it is very inappropriate to ask for gifts.
