Zhen Xi Tea is a registered trademark of Mingxi Tea Industry, and the manufacturers are Anji County IELTS Tea Farm. Founded in 1999, IELTS Tea Farm is one of the first batch of Anji White Tea Geographical Indication Authorized Enterprises, with more than 600 acres of standardized Anji White Tea Garden and 2,000 square meters of standardized processing plant, and passed the QS National Food Processing Quality License Certification and National Green Food Tea Certification as early as 2008. In 2010, the "IELTS" trademark was awarded the title of "Zhejiang Famous Trademark", and the "IELTS" brand Anji white tea was also recognized as a famous brand product in Huzhou City.
 
In the early days, in order to promote Anji white tea, the Anji County Government adopted the management model of "parent trademark" plus "sub-trademark", that is, "Anji White Tea Certification Trademark" plus "Enterprise Trademark", so it can be seen that different tea enterprises use "Anji White Tea" as the brand name for unified management and sales on the e-commerce platform. However, it is worth noting that "Zhen Xi Mingpin", as a trademark, cannot directly search for products on the e-commerce platform, but corresponds to "Mingxi Anji White Tea", and the experience is not very friendly. Zhen Xi Tea is available in self-drinking and gift packs, with a rich selection of different tea grades and weight specifications, and the overall cost performance is high.
