Every school day, Xiang Yuncui gets up at 5 a.m. to make breakfast for her 7-year-old granddaughter, Tan.
Yuncui then puts Tan on her back and, together, they travel 10 kilometers (about six miles) over mountainous terrain to Tan's school in southwest China, a trip that usually takes around two hours, ITN News reports.
Tan has cerebral palsy and can't walk on her own. Over the last three years, the two have traveled about 10,000 kilometers (6,200 miles), according to ITN News.
"Once, my grandma had to run in order to get me to school on time," Tan told NTDTV. "She fell down and bruised her knees. Yet she tried to hide her bleeding knees from my view at the time."
ITN notes that Tan has never been late for school, and Yuncui insists she'll keep making the trek for as long as she can.
Thankfully, the pair's plight has garnered local attention and officials have agreed to perform surgery on Tan to try to make her more mobile.
CCTV reports that Tan's father died in a car accident in 2008. Her mother had to leave home to find a job, and that left Yuncui with the responsibility of caring for her granddaughter.
