During the past summer vacation, a 15-year-old boy named Li Banghua from Hefei, Anhui Province, built a model plane on his own in less than a month. He successfully flew it, surprising everyone around him.
According to a local report, Li had just finished his high school entrance exam a year ago with good grades. After the exam, he immediately started working on the model plane. Li has been interested in model planes since childhood and has been studying how to build them for years. This model plane is the largest and most successful one he has ever built.
Li faced many failures. “But the biggest difficulty was that adults couldn’t understand me,” Li said. “When I said I was going to build a model plane, many adults thought it was impossible. But I decided to keep working hard because once I start something, I won’t give up easily.”
