The refined green tea for export to North Africa must be colored. However, it is always advisable not to color the hair tea. The stems of the colored tea are very unnatural and the color is dry. When soaking in water, there are oily or floating objects on the water surface. If you tilt the teacup, there will be a circle on the edge of the cup. Rub it with your fingers. There are also traces of color quality on the bottom of the leaves. The tea sprayed with paste is dead and dry and has no lustre. Put it on the palm of your hand and breathe, and then press it with the other palm, and it will stick to the palm. If viewed with a magnifying mirror, there are grains of starch, the water color is cloudy and unclear, the color is greasy, the water surface is sticky and foamy, the bottom of the leaves is mostly broken and rough, and it is very easy to turn rancid and has a bad smell.
