So, the two of them were in the small courtyard, each occupying a corner, and started practicing on their own.
After finishing a set of boxing moves, Zhang Xiaohu saw that Zhang Xiaohua was still practicing and stood there with a smile, watching his younger brother practice. Soon, he noticed that Zhang Xiaohua was only practicing that set of moves, repeating it over and over again. He found it very strange, but immediately, he had an idea and shouted, "Xiaohua, stop for a moment, let's have a sparring session."
Zhang Xiaohua briefly paused his fists and feet and said happily, "Alright, Second Brother, just wait a moment, I'll practice a few more times and then I'll stop."
Only after practicing the fixed number of times and feeling the cool stream of bone-quenching appear, did Zhang Xiaohua finally stop.
Zhang Xiaohu asked curiously, "Xiaohua, why do you keep practicing the same set of moves over and over?"
