Huishui Zongzi is widely known in Guangxi, Guangdong and local snacks, Fujian. Huishui Zongzi is golden in color, crystal clear and transparent, suitable for cool eating, and can be used as a cool and thirst-quenching food in summer. Grey water jiaozi is also divided into sweet and salty. There are sesame seeds, peanuts and pork in the salty zongzi. But sweet zongzi has no stuffing and is softer than salty zongzi. It tastes like honey and yellow sugar. Grey water dumplings are made by thoroughly soaking glutinous rice in alkaline water to make it pale yellow, then wrapping it with reed leaves into small four-corner dumplings, tying it tightly and cooking it. Among them, alkaline water is mostly obtained from plant ash burning and firewood ash filtering.
