Who is the ninja with the lunch box?

For reference, Hao Yun's first album "Little Western Heaven in a Peaceful and Prosperous Age" has the following lyrics:

There are many people in the subway station.

They all frowned.

There is a young man with a lunch box in his hand.

His eyes are like ninjas.

This "lunch box ninja" is a colleague of General Yun. He takes a lunch box to work every day and lunch in the morning. He is highly nearsighted, and everyone thinks he looks like a ninja, so he is called "lunch box ninja".
