On the night of May 5, 2009, Ma Gedda had a rare moment of uncontrolled weeping.
In the middle of the night, he heard strange noises coming from his child's room, sounding like a mouse gnawing on something. The sounds came in waves, growing increasingly intense. His child usually slept lightly, so why was there no reaction? A sudden thought struck him. He quietly got up, grabbed a flashlight, and tiptoed into the child's room. When he turned on the light, the sight broke his heart: his child was chewing on the bed frame. The child lay sideways, motionless, with one leg dangling in the air and trembling. It was an unbearable pain, a suffering the child refused to let anyone know... Chewing on the bed frame seemed to be the only way for the child to cope.
Ma Gedda stood frozen by the bedside. Upon seeing him, the child quickly adjusted their position to pretend to be asleep, then laughed, saying, 'Dad, I can't sleep, so I'm just playing on my own. Hee hee...'
Ma Gedda said nothing. He turned and ran back to his own room, crouching on the floor and holding his head. He tried to hold back his tears for a long time, but eventually, like an old ox, he broke into loud sobs. His child hobbled over with their injured foot, embracing their father and urging him, 'Dad, it doesn't hurt. It really doesn't...'
The next day, Ma Gedda found the painkillers in the child's room. There were over a hundred pills. It turned out that the child hadn't taken a single one; they were still perfectly packaged and hidden tightly away. Ma Gedda roared, 'Why didn't you take the medicine?' The child coquettishly replied, 'Dad, this medicine costs dozens of yuan! I wanted to sell it to buy you a new piece of clothing. Look at your current clothes, they're beyond repair...' Felt by both pain and anger, the father forced the child to swallow two pills.
2009年5月5日深夜，马疙瘩经历了一场久违的大哭。
半夜时分，他听到孩子屋里传来奇怪的响动，听起来像是老鼠在啃食什么，一阵接一阵，且越来越剧烈。孩子睡觉通常很轻，为何此刻毫无动静？马疙瘩心中一紧，悄悄起身，拿着手电筒摸索进孩子的房间，打开灯后，眼前的景象让他心如刀绞：孩子正趴着啃咬床帮。孩子横躺在床上一动不动，悬空的那只脚在空中颤抖，那是难以忍受的剧痛，也是不愿让任何人察觉的痛苦……除了啃咬床帮，孩子似乎已别无他法。
马疙瘩呆立床前，孩子看到他后迅速调整姿势装睡，随即笑道：“爹，我睡不着，自己玩呢，嘻嘻……”
马疙瘩没有言语，转身跑回自己的房间，蹲在地上抱着头。他强忍了很久，最终还是像老牛一样失声痛哭。孩子拖着受伤的脚跑出来，抱住父亲劝道：“爹，我不疼，真的不疼……”
第二天，马疙瘩在孩子的房间里找到了那些止痛药，足足有一百多片。原来，孩子一片都没有吃，包装完好，藏得严严实实。马疙瘩怒吼道：“你为什么不吃药？”孩子却撒娇说：“爹，这药要几十块钱呢！我想把它们卖了，给你买件新衣服。你看你现在的衣服，已经连补都补不好了……”父亲又心疼又愤怒，强迫孩子吞下了两片药。
