Jiao Limin is the head of the Kirirom I hydropower plant, mainly responsible for safe production operations and training. After graduating from university, Kong Teayong came to work at the hydropower plant. The biggest obstacle to communication between mentor and mentee is language, as Jiao Limin told his Cambodian mentee, Kong Teayong, "To do the job well, we must overcome the language barrier."

Jiao Limin was determined to help Kong Teayong quickly learn Chinese. Jiao Limin taught Chinese while imparting technical knowledge. Over a year later, Kong Teayong could proficiently communicate in Chinese on familiar topics and had mastered equipment operation principles, safety work procedures, and simple accident handling.

Kong Teayong said, he wants to use the skills he has learned well and work diligently to show appreciation to his mentor.
