At a horizontal table with two rows of computers, many players were concentrating intensely, waving their mice, tapping their keyboards, and fiercely battling with fervor. At first glance, there didn't seem to be anything extraordinary, and I was about to look away. Suddenly, a child dressed in a light yellow T-shirt caught my eye. I wasn't sure if it was the brightness of the child's clothing or the uniqueness of the child's height or age at the venue that stood out, but in any case, this child was very conspicuous among the many players engaged in battle, successfully capturing my attention!
