Being a parent is the toughest job in the world.
You never stop caring for your children and giving them all the essential things they need. Whether your child grows to be a wise one or decides to live on his or her own, your responsibility as a parent doesn't just stop there instantly.
But what if it's the other way around? This is the story of Jia Jia, a six-year-old girl from Ningxia Province of China.
This "little angel" touched the hearts of netizens and instantly became an online sensation for taking care of her paralyzed dad, Tian Haicheng.
Tian uses Kuaishou, a photo-sharing app in China, to document his daughter's selfless work. After the two went viral on social media, Tian's account now has more than 480,000 followers.
