The names Tcha, Tay or Tee mentioned here in fact all came from the Cantonese and South Fujian dialect pronunciations of the Chinese character 茶 "tea" (cha in modern Mandarin). Depending on which port the leaves were exported through for the sea trade, they have gave rise to the different words for tea in different European languages.
這裡所說的 TCHA、TAY、TEE 其實都是中國字「茶」的廣東、閩南方言譯音，視當年海上貿易的輸出口岸，在歐洲各國有不同的稱法。
