Despite the visual problem, Ang has actively explored the world in travels. He believes that travel is not only about sightseeing but also the people and experiences encountered along the way, as well as relevant historical and cultural knowledge.

"Last month, I climbed to the top of the Taishan Mountain via the most challenging route. I set off at 11 pm and reached to the top at around 3 am the next day, waiting to see the sunrise," Ang said.

"I feel the sunrise on my face. The temperature on my skin can tell me when the sun has risen," Ang added.

Ang's positive attitude and energy also serve as a source of inspiration for those around him.

Dong Shiyuan, one of his classmates, said, "Ang's perspective on life is unique, which offers us many unique insights and experiences that allow us to view life from different angles."
