You said that Jiajing’s training is good, do you mean that they use cake oil to beat and then use it as a decoration practice, but it is not good to waste time and practice, or that they only teach baking once and practice by yourself. If you provide the ingredients yourself, is it good for the teacher to charge a fee, or is it good to teach the bread that is not yet cooked but have the nerve to buy it for the students to taste? /,
