2 - In many Asian cultures, two is good luck. It is thought that good things come in pairs, which is a phrase that even appears in Western culture. It is used often in advertising or on menus in restaurants by saying that a product is doubly effective or it will bring double happiness. In Cantonese, the number two is pronounced much like the word easy, hence it is considered good luck there, as well. There is an emphasis on the number two in Western culture, as well, but not relating to luck.
