Chinese pre-wedding customs are traditional Chinese rituals prescribed by the Book of Rites, the Book of Etiquette and Ceremonial and the Bai Hu Tong condensed into a series of rituals now known as the 三書六禮 (sàam syù luhk láih) (Three Letters and Six Rites).[1] Traditionally speaking, a wedding that incorporates all six rites is considered a daaih chéui (complete wedding, dà qǔ).[2]
