1, New Oriental Snack Training has been tested by the State Food Safety Administration and has a national certification certificate, while Changchuang Snack Training has not been tested by any institution and has no certificate. The former is formal, which is one of the reasons.
2. The teachers of New Oriental Snack Training are all senior chefs, China, with a chef's certificate, while Changchuang Snack Training is all chefs of small restaurants, without a chef's certificate, so the former is more formal than the latter.
