The packaging of Chinese cabbage tea usually has the OFDC logo and a Chinese cabbage printed on it. In addition, a seal can be seen on the right side of the tea cake, which says Four words: "Tea King Green Cake". Not only that, there is also Neifei in Chinese cabbage tea, namely Banzhang Arbor tea.
