The seven necessities stem from the phrase "Firewood, rice, oil, salt, sauce, vinegar and tea are the seven necessities to begin a day". The items were known as early as the Song dynasty travel book, Dreams of the Former Capital.
The Chinese phrase "seven necessities" literally means "é open é door 丠seven 件亠items" when translated, which is an old Chinese saying. They include firewood (æ´ chái), rice (ç±³ mÃÂ), oil (æ²¹ yóu), salt (é¹½ yán), sauce (é¬ jiàng), vinegar (é cù), tea (è¶ chá). The seven necessities were made popular in modern tea culture due to the fact the beverage was mentioned as one of the seven necessities of Chinese life.
