On February 14, 2023, after a snowfall, Lanzhou City in Gansu Province in western China was covered with snow and the air was fresh. Ren Zelin, an Iranian student studying at the School of Civil Engineering and Mechanics of Lanzhou University, came to the library to study through thick snow. This is the sixth year for him to study abroad in China.

In 2023, the 27-year-old Ren Zelin came to the School of Civil Engineering and Mechanics of Lanzhou University in 2018 to study for a master's degree. After completing the master's degree in 2022, he continued to follow Professor Huang Ning, an internationally renowned expert in wind and sand physics research, to engage in soil desertification prevention and control, etc. Research and start your doctoral study career.

In Ren Zelin's view, like other arid and semi-arid countries, Iran also faces environmental problems such as land desertification. China has contributed its strength to the world's desertification prevention and control work, which is very worth learning from. Through years of in-depth study and research, he has learned a lot of new technologies and ideas for China's desertification prevention and control. Ren Zelin hopes to make some high-level achievements in the field of research, contribute to international exchanges on desertification prevention and control, and become an ecological ambassador who spreads green ideas.
