During a period of nine days, those who are participating in the festival dress all in white and gin je กินเจ, which has come to be translated as abstinence from eating meat, poultry, seafood, and dairy products. Vendors and proprietors of restaurants indicate that je food is for sale at their establishments by putting a yellow flag out with the word เจ (je) written on it in red. However, technically, only food prepared in the sacred kitchen of the Chinese temple (in Thailand, called san jao ศาลเจ้า or ahm อ๊ำ) is je, as it must undergo a series of rituals before it can be given that name.
