What is the last sentence of the two-part allegorical saying "Don't steam steamed bread"

There are many versions, such as "don't eat steamed bread to fight for breath", "don't eat steamed bread to fight for breath", "eat steamed bread to block breath" and so on. This is actually not steaming steamed buns for breath. This is a folk allegorical saying, the whole sentence is to buy a steamer to sell children, not to steam steamed bread. We usually say we don't steam steamed bread, and there is a homonym here.
