There is a whole range of them, more than what's listed in that article. They seem to not list some made kinda like boloney but using fish (overly processed to the point you can't tell what protein is used). Lup cheong has several versions. Personally I don't really like the version that mixes liver with the meat (for me it makes the sausage grainier), but it makes for a quick meal (rice, lup cheong and some vegetables) if nothing else..
