Loss.
Everyone has to have experienced loss at one point in their life.
Jian must have, too. However, he never necessarily felt that his losses were greater than his victories. At the end of the day, the amount of times he won couldn't be compared to the minor losses he had in life.
Of course, he also knew that loss was inevitable.
The death of his goldfish during first grade.
The passing of his grandma after a year-long battle with cancer.
Maybe even the B+ grade he had for not studying the material the night before.
However, he had come to accept all of these pretty quickly.
Not because he was the resilient type but because they were expected.
Death had to happen.
His grade was still the highest even though it was a mere B+.
However, for a long time, basketball was the one game he had always dominated.
