Five Hundred Yuan Under the Pillow

In 2036, the genius physicist Lu Beichen stood at the top of the world's science. People only knew that he invented the "quantum retrospective imaging" technology, but no one knew that it all stemmed from a private obsession - he wanted to see his mother again. The mother, Li Xiufen, was a frugal rural woman who raised her four sons frugally. Lu Beichen is the third eldest child and is the one whom his mother loves the most. In my sophomore year of high school, my mother passed away due to illness, leaving no video records. In the following ten years, that longing was like a black hole, swallowing up all his warmth, but pushing him to the forefront of physics. This is a story about longing, regret and silent farewell. No matter how cold technology is, it can't be as cold as the bowl of sugar-watered eggs that my mother kept warm.
