These are fun.
Most (around 440,000) of the Gelao ethnic minority (仡佬族 - gē lǎo zú) live in Guizhou Province to the north-west of here. There are also approximately 3,000 in Vietnam. They do have their own language, unrelated to Chinese, but very few (<1,000) still speak it today.
They eat some of the spiciest food in China, including these tiny sausages.
7cm / 3¾" long, they come pre-cooked, so ready-to-eat. Ferociously spicy yet still almost salami-like in flavour. These are a favourite beer food!
