You can find sausages on Taobao (best to search under their Chinese name) but they are of
varying quality.

TaoBao is 'God' in China! The sausages I have seen there are not what I'm looking for. I had a quick look at 'fieldsofchina' and there's one brand there called 'Elders'. Seems quite popular insofar as they have many of their products, but I've never heard of them.

Thanks for the link by the way!
