First of all, find more training institutions before signing up, and make telephone consultation on issues you care about, such as training type (whether it is suitable for your own time schedule), training fees, class hours, course content, teaching environment, instructors, certification, etc. , to see if these meet the standards.
Then, make a field trip to the training site before registration. Main concerns: 1, qualification of training institutions, and whether the school license has the qualification and charging standard for training tea artists; 2. Visit the training ground.
Finally, I suggest that you have a chance to listen to a class and feel it. Generally, formal training institutions are allowed to listen once.
