After my brother was rescued, he developed a high fever that left him with the intelligence of a four- or five-year-old child, despite being only seven years old at the time. He looked at his sixteen-year-old brother, who would cling to him and call out for him every day. At that point, he hugged Brother Zhang and burst into tears. After that, he took on the role of the big brother.
But the sixteen-year-old brother suddenly became as naive and oblivious as a four- or five-year-old child, knowing nothing. When he went to school, he was bullied by his peers every day. If it hadn't been for Zhang Mingliang accidentally walking in on Zhang Mingming taking a bath, their family would not have discovered Zhang Mingliang covered in bruises. Aside from his face, his body was mottled with blues and purples, some of which were merely faint traces, but it was apparent that these injuries had been inflicted not long ago.
