Shoots rather stout, green in color with average amounts of fine hairs. The weight of 100 one bud and three leaves leaves shoots averaged 71g. The peak period of flowering stage appears in the first ten days of November. With abundant amounts of flowers and high bearing percentage. With rather higher resistance to drought and frost (it was uninjuried under the conditions of absolute minimum temperature of -8°C). Moderate resistance to diseases and insect pests. High rooting ability during cutting propagation.

        High yielding. According to the results of varietial comparative experiment carried out in 1977~1984，the yield of made tea averaged 237.8 kg per mu, and 26.2% higher than that of Ningzhou variety.

        According to the analysis conducted by the Jiujiang Tea Research Institute, Jiangxi province, the contents of tea polyphenols in the one bud and three leaves, shoots averaged 24.97%,water extracts 41.69%.
