《明史·志·卷五十六》
现在减轻通番之罪，仅只是充军，禁止内地之茶，使他们不能食用，又使商人私自征收茶，全部聚集在三个茶马司。
今减通番之罪，止於充军。禁内地之茶，使不得食，又使商私课茶，悉聚於三茶马司。
Now the punishment for collaborating with the 番 has been reduced, and only military service is imposed. The inland tea is prohibited, making it unavailable for consumption. Merchants are allowed to collect tea privately, which is all concentrated in the three tea-horse bureaus.
