Baojian is made of bamboo shoots with buds in front of beginning of spring. Slices are smooth and round, yellow and white, and the meat is fresh and tender. It is the top grade of magnolia slices. Full, tender and crisp, it looks like a pagoda and a dragon horn, so it is also called "Golden Pagoda" and "Dragon Horn".

"Winter slices" are winter bamboo shoots before "rain". They are divided into two halves, flat and smooth, white, thick, soft and closely spaced.

"Peach slices" are made of bamboo shoots that have not been unearthed before "Jing Zhe". They have smooth side, dense pitch, root tip, slightly thin meat and fresh taste.

"Spring flowers" are made of spring bamboo shoots from "vernal equinox" to "Qingming", with sparse pitch, drum-saving, thin bamboo shoots and older quality. These four varieties have their own characteristics, and their production techniques are very particular. Judging from the quality of Yulan tablets, Baojian is the best, followed by Dongfang tablets, Taopian tablets and Chunhua tablets.
