Classic series
Classic series tea products are the most basic and important part of Dayi product structure. The four dimensions of sales volume, market coverage, brand influence and cultural connotation ensure the leading position of Dayi Group in the tea industry.
Packaging evolution
When 7572 was first introduced to the market in the mid-1970s, it was packaged with cotton paper and seven-seed cake instructions, which was the standard of Menghai Tea Factory. The package is "China Tea Brand" with the words "Produced by Menghai Tea Factory" printed on it. After the mid-1990s, the packaging cotton paper, inner fly and instructions of 7572 Qizi cake have basically been changed to "Dayi brand" patent trademark, and the words "Menghai Tea Co., Ltd." are printed on the inner fly.
