Do middle school students eat wake-up bean snacks?

All right. Wake-up bean is a small package of 9 pieces, which can be eaten immediately and chewed with coffee candy to refresh the students who are sleepy in the office. The purpose of waking beans is to escape the residual carbon dioxide in coffee beans, contact with air, accelerate oxidation, and use the principle of oxidation to remove the unpleasant bitterness of coffee beans, so that the flavor is more round and smooth.
