This could be a silly question, but what the heck! Now I'm not totally new to tea, I've been floating around the tea world for a year now and I've learned so so much and tried some outstanding teas along the way. But something caught be off guard recently!
I've seen puerh tea vendors selling compressed white tea, and calling it white tea. I've seen people calling what I thought was white tea sheng. This confused me, simply because the white tea was being associated with puerh in terms of the section of the shop it was sold from. Today I received this months global tea hut which came with a sample of some very nice and fresh tea buds, which were labelled as sheng tea buds.
Now my knowledge is that sheng translates there or abouts to "raw", which I always assumed referred to tea processed in a certain way for ageing naturally. White tea of course is for drinking fresh (or so I thought)? These buds were very interesting, a bit unlike the buds usually seen in white tea, but very nice.
So yeah, sorry if this is long winded, but the question is, can white tea be called sheng, and if so, what exactly can we define sheng as, if not always related to puerh?

EDIT: I am aware of how white tea is processed, or not processed in many ways compared to other tea. But I guess my point is, puerh is processed to keep undenatured/not destroyed enzymes that help the ageing process, but I thought white tea was not like this.
