1. Wash, drain, chop and freeze. Wash shallots, drain the water (be sure to dry them thoroughly to avoid caking after freezing), cut them into chopped green onions, put them into fresh-keeping bags/boxes/beverage bottles, and freeze them.

2. Bury the soil, water it, put the fresh onion directly in the wet flowerpot that has been loosened, and put it in a sunny place, but don't expose it directly, let it grow by itself. When eating, cut off or pinch off the green onions, and the remaining roots will continue to grow new onions, but they are thinner than one crop.

3. put it in a bottle for hydroponics. Wash the soil of fresh shallots, put them in a glass bottle with half a glass of water and put them by the window. Change the water every two or three days, remove the rotten roots when you see them, and pinch the onion leaves every time you eat them, which is very convenient. You can also watch it as a bonsai and keep it for a week.
