To study aromatherapy in China, you can obtain the certificate of senior aromatherapist and the certificate of aromatherapist teacher issued by Ministry of Human Resources and Social Security. These two certificates are common in the whole country and valid when going abroad. You can check them on the official website of the country. At present, only China has issued this professional certificate in the name of the country, and other countries have issued it by industry associations. If you want to learn the professional knowledge of the system, I recommend you to go to Flora Aromatherapy College, where there are well-known experts at home and abroad. They are the developers of this major and are also responsible for the national teaching materials and national question bank of this industry, which is very authoritative.
