Gansu Normal University for Nationalities is located in Hezuo City, the capital of Gannan Tibetan Autonomous Prefecture, at the border of Gansu, Qinghai, and Sichuan provinces, which is the gateway to Tibet in mainland China. The university is the only provincial-level normal university for ethnic minorities in Gansu Province. It was founded in 1984 and was upgraded to a regular undergraduate institution in March 2009 with the approval of the Ministry of Education. The school covers an area of 890.3 acres and has 16 faculties (departments) with 40 undergraduate majors.

In May, Greelan Technology Development Co., Ltd. (hereinafter referred to as "Greelan Technology Company") reached a cooperation agreement with Gansu Nationalities Normal University for two sets of voice teaching systems. The digital voice room system has broken through the technical barriers and cost limitations of hardware based voice classrooms in practical applications. Based on computer networks, with just one system installation CD, a professional teaching environment integrating voice classrooms, multimedia classrooms, examination centers, and other functions can be established, simplifying the school's procurement, scheduling, use, maintenance, and upgrading work to the greatest extent possible, significantly reducing investment costs. The digital voice room system introduces various multimedia information such as audio and video frequency, graphic images, animation, and text, as well as real-time dynamic control, into the teaching process. The teaching methods are more comprehensive and advanced than traditional voice classrooms. The Greelan engineers have completed the installation and debugging on June 18th, and quickly put the customer into use.

Greelan Technology Company has always adhered to the concept of "positive, simple, happy, professional, honest, and win-win" to serve customers, and to give back to users with fast, efficient, and high-quality products, which has also led to more and more domestic and foreign customers choosing the "Greelan" brand.
