According to the inquiry, in traditional cooking in China, cooking is regarded as "frying art", and the seemingly lively frying area in the supermarket is the specific scene of frying art, and skilled chefs usually cook with only the first three fingers. This skill is called "Le Zhu", and Le Zi means the first three fingers. Therefore, music cooking uses the first three fingers.

Technically speaking, "Happy Cooking" is not learned overnight. It takes repeated practice and at least dozens of bowls of dishes to be proficient. Doing more can master movements, techniques and relationships, and achieve advanced cooking skills.
