Hakka people in Taiwan Province Province have a kind of zongzi which is boiled first and then wrapped. How to make them?

There are two kinds. I don't know which one you are talking about. I will provide them to you. ...

1. Zongzi: Steamed glutinous rice is wrapped with shrimps, red onions, pickles, shredded mushrooms, pork and other materials, then wrapped with sun-dried bamboo leaves and steamed.

2. Braised jiaozi: Soak glutinous rice in water, grind it into rice slurry, drain it, knead it into dough, add pickled vegetable spices and steam it with bamboo leaves. It takes time to make, so the taste is quite special.
