Wong lo kat

Wong Lo Kat , or Wanglaoji in Mandarin pinyin, is a Chinese herbal tea, and one of the most popular tisane drinks in China today. It is sold in many forms and different types of cans or cardboard containers. Wong Lo Kat contains a number of herbal infusions and decoctions, as well as sweeteners: "Wong Lo Kat" is the Cantonese transliteration of its name in Chinese characters. Wong Lo Kat originated in 1828 during the Qing Dynasty in Guangdong (Kwangtung) and Guangxi (Kwangsi) provinces of China, founded by a doctor Wong Chat Bong (simplified Chinese: 王泽邦; traditional Chinese: 王澤邦; pinyin: Wáng Zébāng). Because the Wong family was the inventor of herbal tea brewing in southern China, the brand is synonymous with this type of drink. The recipe has been passed down through multiple generations to today's tea culture.
