Performing formal bows by the bride and bridegroom is also called "worshipping the heaven and earth". Actually, it includes bowing to the heaven, earth, ancestors, parents and the bride and bridegroom bowing to each other. Before the ritual, candles, incense, memorial tablets or portraits of ancestors should be placed in the main hall, where there are grain buckets stuck with the character of "double happiness" holding various grains, peanuts and red dates etc. Then, candles are lit, incense burnt, firecrackers exploded and music played.
