Lei cha (Chinese: 擂茶; pinyin: léi chá; literally: "pounded tea"; pronounced [lěi̯ ʈʂʰǎ]) or ground tea is a traditional Southern Chinese tea-based beverage or gruel. The custom of Lei cha began in the Three Kingdoms period or even Han Dynasty. It is very prevalent among Hakka people in Hakka regions of Taiwan. It is brought by Hakka people to Taiwan, Malaysia, and any locales with a substantial Hakka diaspora population. Besides Hakka Lei cha, Lei cha is also very traditional among Hunanese people in Northern part of Hunan Province of Mainland China. So, the Lei cha custom in China has two different kinds: Hakka Lei cha; and Hunan Lei cha.
