The characteristics of China tea brand Yin Hongyuan Tea are a batch of high-grade Pu 'er tea produced by China Tea Company in the 1940s and 1950s. Round tea, also known as modern Pu 'er tribute tea, was first made in 1940, when Fan founded Fohai Tea Factory, and continued until the end of 1950s. The inside and outside packaging of Yin Hongyuan Tea are all red signs, and the logo of "Bazhong Tea" of China Tea Company is printed on the front of the outer wrapping paper. In the circle of eight Chinese characters, there is a red word "tea", hence the name. Among Pu 'er tea products produced by China Tea Company, only Hongyin Round Tea and Hongyin Yunnan Tuo Tea have the words "Bazhong Tea" and "Black Tea", which shows their preciousness. In addition, Yin Hongyuan Tea also witnessed the transformation from Fohai Tea Factory to Menghai Tea Factory, so it has special commemorative significance in the history of Pu 'er tea.

Red-printed round tea can be divided into "early red printing" and "late red printing" according to the different graphic fonts printed on the outer packaging paper of tea cakes. Because woodblock printing was still used at that time, after the woodblock was used for a long time, the fonts on the woodblock would have burrs and needed to be trimmed. The symbol font and strokes of "Eight teas" in "Early Red Seal" are thicker, but the font of "Late Red Seal" is slightly smaller with knife marks. On the packaging, the bamboo chops used in "Early Red Seal" are thick, old, hard and dark in color, while those used in "Late Red Seal" are tender, thin and light in color. In terms of aroma, spearmint is the "early red seal" and camphor is the "late red seal".

Both kinds of round tea are green tea produced in Mengla, with thick leaves and full strings. The color of tea is chestnut red, the tea surface is shiny, the tea soup is red, and the leaves are soft and fresh. Old-fashioned mold production, the inner fly is completely buried in the center of the tea cake, and the navel-free round cake tea is comparable.
