As an important item in wedding preparation, the happy word has become an essential element in the wedding. It is said that Wang Anshi wrote two conjoined happy characters on red paper at the wedding ceremony and when he was the number one scholar, and posted them on the door.

When people get married, they will paste the word "double happiness" on doors, windows, halls and bridal chambers in order to get married.

Happy characters pay attention to pairs. If it is a single room door, both sides of the door should be pasted with happy characters. Even numbers are also suitable for decorating happy characters at home to get a good title. According to different habits, brides in some areas will add odd numbers to their happy words. )
