In the past decade, international students have mastered new technologies at Lanzhou University and brought what they learned back to their home countries.

This year marks Kenyan student Kiprotich Wesly Cheruiyot's tenth year at Lanzhou University. During his doctoral studies, Kiprotich often accompanied Professor Xiong Youcai to farms in Africa to promote ridge-furrow plastic film mulch technology.

"For Kenyans, there are two major projects built by China, the Mombasa-Nairobi Railway - the first modern railway in Kenya since its independence - and the ridge-furrow plastic film mulch. I want to bring this technology back to my hometown," said Kiprotich.
