High quality material from different Yiwu villages was used for this tea, which has transformed well with the passing years in perfect CYH brand storage.
Excerpt from the review on puerh.blog:
While the 08 Cang Yi is, as described, very coarse and quite astringent for a Yiwu, the 07 Cang Yi is much softer/milder and far less astringent […] this makes it more pleasant to drink at the moment (at least for me), but the 07 also has significantly less Qi than the 08. It almost seems as if they experimented with two different approaches: the 07 as a super smooth boutique Sheng and the 08 as an old-school, more traditional Sheng in the direction of Zhen Chun Ya Hao.
