In the Yuan Dynasty, in addition to frying, there were other cooking methods, such as salt frying, crisp cooking (formula of Ruizhutang experience), wine boiling (health treasures) and oyster frying (Danxi heart method).
In the Ming Dynasty, the processing methods such as salt fennel frying, Lygodium japonicum silkworm frying, crisp frying and bran frying (Puji recipe) were added [2].
In the Qing Dynasty, in addition to steaming wine, simmering noodles, frying bran and other methods, processing methods such as fire roasting (surgical be adept at), fire storage (surgical treatment) and salt water soaking (medical records) were added [2]. The purpose of the processing is also described, such as "clearing fire for raw use, curing hernia and simmering, and steaming to pain wine" (Depei Materia Medica) [2].
At present, the main processing methods are fried yellow, fried coke, salt baking and so on [2].
