The steps are as follows:

1. Cut the scallions into half sections, and cut the ginger into three slices diagonally;

2. Put the ginger and scallions into the pot, and then Add one tablespoon of brown sugar, two cups of water, and cover the pot.

3. Bring to a boil over high heat, then turn to low heat and simmer for three minutes, then turn off the heat, and then simmer for another ten minutes.

When using scallion soup or ginger soup to dispel cold and sweat, you should first eat something, such as hot porridge. Never let your child sweat when his stomach is empty. Only when his stomach is full can he sweat better.
