Who brought Tieguanyin, and when
The Taiwan Tieguanyin article credits both 張迺妙 and 張迺乾 with bringing plants in 1895; Zhang Naimiao's biography gives 12 plants in 1895, 1,000 in 1896, and an undated purchase of 3,000 with 張迺乾. The general Taiwan tea article simply places the brothers' introduction in the Japanese era (which began in 1895).
