4. Garlic
Garlic is native to the region of southern Europe and central Asia. During the Western Han Dynasty (206 BC-AD 24), Zhang introduced the species in the onion genus, Allium, to China. During ancient times in China, foreign tribes were referred to as "Hu troops", so garlic was originally referred to as "Hu garlic".
