Lee Barrett is a British vlogger living in China. He came to China in 2007. During these years, he visited many cities and areas, such as Shanghai, Shenzhen, and Xiongan New Area in Hebei Province. He witnessed the significant changes taken place over the decade in China, such as the better road system and more convenient payment methods.

What impressed him most is China's efforts in clean energy applications, such as the use of electric vehicles, large solar or wind power plants he discovered in many cities.

"My eyes are just wide open to the technology and advancements they're making to make the environment cleaner and really driving technology to do that," Barrett said.
