I'm the anon who posted some weeks ago about going on a business trip to China. So here is how that went regarding /tea/:
Most places serve you tea without much asking, similar to the US where you always get water served. 1st hotel restaurant had plenty tea selection, I opted for some silver needle white and got it served grandpa style (annoying, leaves floated on top) and got hot water top ups. 1st business contact served me green tea grandpa style without asking and also did hot water top ups. 2nd business contact did not serve tea but pic rel. Most restraurants either served green, white, black ("red") or barley wheat tea, mostly in a western tea pot with a strainer. I did not come across any Puer in the wild but people know what it is and tell stories of their cakes at home.
Went to 3 tea stores, they were all quite small with limited selection of puer cakes, I spotted some really expensive ones tho. Shops are more focused on lose tea and sealed pressed mini pucks for convenience, which are very popular. Shops would engage you in tasting sittings, where they serve it with a gaiwan. There are some nieche puer shops for sure but did not look into it.
Factory cakes I got:
2008 Long Yuan Hao Sun-Dried Mingquian Sheng by Xishuangbanna Gucha Mountain Tea Co. (Cake is brown like Shou but it is clearly labeled as Sheng)
2018 Menghai Big Tree Sheng by Menghai Bajaoting Tea Co.
Other stuff:
Hand full of 6g sealed white tea mini pucks
Hand full of Chen Pi (this one is really fresh with strong citrus smell in the box. The other ones I saw before were old and stale)
Grandpa Style mug, which has a half round glass sieve in the top, which I thought was really convenient.
Some ultra fancy cup in a gift box
