I'm interested to hear any bits of information on the puerh and other tea production by the Guangdong branch of the CNNP (later transformed into the Guangdong Tea Import and Export Co.). Namely any information about the Guang Yun Gong puerh cakes and Golden Sail (Jin Fan) Brand products, which are still being commonly sold in chinatowns (http://www.tea-gd.com). And about the bit more obscure Bao Ding Brand (Shantou Yihua Tea Exp. Imp. Co.).
Also what kind of material was (is) used? There's been some suggestions that some of their puerh tea did not come from Yunnan and strictly speaking should perhaps not be called puerh... (https://www.teachat.com/viewtopic.php?t=13020)
EDIT: "After 1973 Yunnan stopped exporting tea leaves to Guangdong ... Since 2008 only tea made in Yunnan can be called pu-erh." http://teadrunk.org/topic/17/guangyun-g ... anslation/

Here's some information about the Guang Yun Gong bing:

And a picture of some old tea, Golden Sail Brand:

can't offer any insight about the older stuff, but I have had the Golden Sail orange box Pu. Super broken bits, no real depth of flavor aside from dark and woody, but for some reason I do like it and tend to keep it around the house. Cheap as hell, but somehow I have had worse. Best brewed in a bigger pot once to make one strong mug. But yeah I would be super suspect where the material is from - given how broken up it is I don't think they are too discriminating. I haven't tried the green box yet, I am guessing it is supposed to be like one is sheng and the other shu, but I have heard there is little to no difference. When I started learning about Liu Bao and Shu and Liu Bao being sold as low grade Pu I can very much believe it seeing material like this.

The Golden Sail tea bags you see here a lot, but the Chinese grocery options even for those styles of tea here are pretty poor- finding Sea Dyke can be tricky with it disappearing from shelves for a while from time to time. I have seen some photos of newer boxes of the Golden Sail Liu An, labeled as Lok On. I think it is mostly stems and I don't expect anything amazing but I'm curious to try it. Putting away cheap tea can make for an interesting experiment. I doubt it will show up around here though.

Ya, I've had the green box and the green tin several years ago when i started to drink tea. Not sure what or if there's a difference to the orange box. Also the Special ripe tuo (yellow and green box), which i think was quite decent, but i dont really remember. They used to produce sheng puerh until at least the 80's, not sure if they still do, or when did they stop.
