Sweet fried Chinese spring rolls are often filled with what paste?

Sweet fried Chinese spring rolls are often filled with red bean paste.

The filling is a smooth, sweet paste made from cooked red beans—commonly azuki beans—combined with sugar. It gives the rolls a dense, creamy interior that contrasts with the brittle, blistered wrapper produced by frying. This sweet style is distinct from the savoury spring rolls more familiar outside China, which commonly contain vegetables and sometimes pork.

Red bean paste is a widely used Chinese confectionery ingredient. It also appears in tangyuan, sweet zongzi, steamed buns, cakes and many other East Asian sweets. Its presence in a fried spring roll is therefore part of a broader dessert tradition rather than an unusual substitution.

Taro, lotus seed and sesame pastes are also legitimate fillings in Chinese and other East Asian desserts, so they can sound plausible. However, red bean paste is the conventional answer for the sweet spring-roll description used here. The exact filling varies by region, recipe and vendor.
