Dayi red ribbon was first used to distinguish different specifications of domestic sales and export sales. It is difficult to verify the date of occurrence now, probably in the middle and late 1990s. In the early days, the trademark of "Dayi" was not used, but "China Tea" was used. Later, the use of red ribbons in products was entirely to commemorate the significance, or to show good quality, which had no practical significance.

At present, the red ribbon of Dayi usually refers to the 7542 green cake of 1996. The market price will vary according to the storage conditions and appearance of tea products, and the approximate transaction price is around 1500 yuan.
