Why does Degang Guo always eat garlic?

Garlic contains thiamine, riboflavin, nicotinic acid, allicin, citral and trace elements such as selenium and germanium. It contains about 0.2% volatile oil. The main component of volatile oil is allicin, which has bactericidal effect, so eating garlic is good for your health. It's a big smell.

Garlic is more acceptable to ordinary people. Add thyme, basil, oregano and other exotic spices, and people will not know so much.

Lao Guo weaves garlic into jokes to create the effect of shaking the burden, which is the need of the plot. Lao Guo and Zhou mentioned garlic in their jokes. This is also the origin of the allusion of garlic VS coffee.
