Momo, a 5-year-old child who has been fighting leukemia for nearly two years and has undergone 17 chemotherapies, had many netizens tearing up when he told his mother to "have another child just like me when I'm gone."

"I couldn't speak at all when I heard what he said." Momo's mother told China's Central Television (CCTV). 

She said that Momo has always been a sensible and strong child. "When he first got sick, he didn't even know how to clamp the thermometer. Now even when going through a lumbar puncture, although he cries and shout 'it hurts to death', he doesn't move at all.'' 

"I can feel my heart aching and tears rushing down," commented a netizen on China's Twitter-like platform Sina Weibo. "It is a blessing to have such a wonderful kid. I hope he recovers soon."
