Grape-like fruit generally refers to raisins. Tizi, also known as American Tizi and American Grape, is one of the grape varieties. The raisin has the characteristics of crisp pulp, large fruit, moderate sweetness and sourness, and low requirements for storage and transportation, so it is also called "the king of grapes".

The name Tizi comes from Cantonese. In traditional Cantonese, all grapes are called raisins. After imported grapes are distributed to all parts of the country through Cantonese, people outside Guangdong call imported grapes raisins for convenience.

At present, there are two main varieties of raisins introduced and cultivated in China, one is Italian and the other is Moritani seedless. Among them, Italy is characterized by high yield and fragrance. Sengu is seedless, and the fruit has no seeds.
