Some Star Products during 7542 Series.

In last century when all puerh tea factories had been nationalized and belonging to CNNP (full name: China National Native Produce & Animal By-Products Import & Export Corp.), for the standardization of puerh tea industry, they started to use a unique number to name each kind of tea product produced by certain recipe, tea material grade and tea factory. Around from 1973 year and till 3 years later, this unique product number had been finally established officially and recognized by domestic and abroad market too. 

On this "7542", "75" means this recipe was initiated in 1975 year, the next "4" means this recipe uses the 4th grade tea materials as the main component, the last "2" means this tea is produced by "Menghai tea factory". 

There are some Star Products during history of this "7542" series, like the 1st one below: 

1) "88 Qing Bing" 

(also written as "88青饼","八八青饼", "88青" in Chinese character or "88 Qing Bing" by Pinyin or  "88 Green Cake" in English. )

(pic source:

It is generally taken as "7542" produced during around from 1988 to 1992. Some of this tea had been stored in relative dry storage in HK and the taste turns much better after years of aging and well recognized by market gradually from then on. 

After long time of aging, the aged flavor is obvious and lingers long. Amber color tea soup with brightness and clearness. Sweet taste. Long lasting tea flavor in mouth and deep into throat. 


2) "94 Shi Ye Qing"

(written as 94 事业青 in Chinese character)

 (pic source:

Produced in 1994 year. Since the traditional Chinese Character "枼" (leaf) was wrongly printed as "業" (business), so it got this nick name "94 Shi Ye Qing" or "94 Qing". It is not so famous as the 1st one "88 Qing Bing". 


3) "96 Zi Da Yi" (Purple Dayi)

"96 Zi Da Yi" was published in 1996 year and seems like the 1st product using newly registered brand name "大益" (Da Yi or TAE TEA). Since the words on the wrapper were printed using purple color, so it got this nick name "96 Zi Da Yi" (96 Purple Dayi). Or called as "Rose Da Yi" since the purple color looks much like rose color. 

The inner paper file "Nei Fei" pressed into this tea cake was printed using reddish color. 

 (pic source:

There are other "Zi Da Yi" after 2001 year also published using purple color on wrapper. But also the mark and word on "Nei Fei" are also purple color. 


4) 97 Shui Lan Yin (97 Water Blue Mark)

 (pic source:

 It uses thin wrapper and since the Chinese character "茶"(Tea) was printed using water blue color, so it got this nick name "97 Shui Lan Yin". 

Well aged with old tea flavor. Plum fragrance. Huigan (returning sweetness) and saliva producing both last very long. 



5) "Wu ® Hong Da Yi" (Red Dayi without ®)

Produced in around 2000 year, since at the time Menghai tea factory tried to Register "Da Yi" as brand but hadn't gotten official certification yet. 

There are two kinds of tea with different printed word of "CHI TSE" (Seven Sons) and "CHI YSE" which was wrongly spelled.

 (pic source:

Also since there was white strip bound on each outer bamboo basket (like usage of carton), so it got this nick name of "Bai Bu Tiao". There are 7 Chinese Characters of "责任公司说明书" (Introduction of Liability Company) written by hand on that white strip. Also there is word of "有限责任公司"(Limited Liability Company) printed on  "Nei Piao" (Inner Paper File).
