Wash the rice, soak it for one day, and grind it into rice slurry with water (you can also use a grouting machine). Heat the rice slurry in a pot, and at the same time add a proper amount of edible alkali (soil alkali cooked by burning ash from tung tree shells), stir vigorously until it is cooked, then put it in a pot for cooling (don't touch it when cooling, otherwise it will go bad), put it in a plate when eating, and then put the cut kohlrabi, pickles, crisp soybeans, crisp peanuts and chopped green onion into it.

Millet residue:

Buy millet first, preferably waxy yellow (but be careful not to add pigment). Then wash it, soak it in cold water for about a day and a half, and change the water every once in a while.

Buy pork belly (fat, with skin, so that it will be waxy when steamed, and the meat will not be greasy when steamed), wash a whole piece, fry the skin in oil until golden, and then cut into nails.

Add the soaked rice and meat into the red pond foam, mix them evenly, put them in a bowl (without a plate) and steam them in a pot until the fat melts. Rice looks yellow, so just stick each grain together. When you eat it, you can put it upside down on a plate to look good. But remember not to steam for too long next time, or there will be water flowing backwards.

Another simple way is to buy it from Five Blessingg, which is also delicious. There should be some in the supermarket.

These are just my methods, I hope I can help you.
