Zhang Xiaohu casually threw the Erlang Boxing manual onto the Kang (heated brick bed).
After dinner, Zhang Xiaohu still practiced his Liuhe Boxing under the oil lamp, while Zhang Xiaohua watched in boredom. He found it strange that it was just a set of Liuhe Boxing, with only that many moves repeating back and forth. What was there to practice? His second brother treated it like a treasure, practicing it over and over, sometimes quickly, sometimes slowly. Was it really effective? He had his doubts.
Extremely bored, he picked up the manual by the Kang and began to flip through it under the dim light. Suddenly, he let out an "Eh" and stopped at a page. Hearing the noise, Zhang Xiaohu, who was practicing, asked hurriedly, "What's wrong, Xiaohua?"
"Oh, Second Brother, I saw something strange." Zhang Xiaohua explained, "Bring the oil lamp over here."
