The national unified examination is divided into five grades: junior tea artist, intermediate tea artist, senior tea artist, technician and senior technician. So you should know the difference between a senior tea artist and a senior technician. The level needs to be tested online from the primary level. Starting from a senior tea artist, there are restrictions on the conditions for entering the exam, at least 25 years old and more than three years of work experience.
