A tea artist's professional qualification certificate is a piece of paper. You won't be a tea artist if you take a training course and get a certificate.
How to take the exam?
Apply to a professional tea artist training institution first.
They will help you get the certificate easily and quickly.
This certificate has deviated from the essence of a tea artist, whose duty is to make tea well.
The certificate of a tea artist is to perform the tea-making process well.
