HARBIN, CHINA — Xiao Cui is an 18-year-old high school student from Harbin, China, but you probably won't believe that, it's all due to his mysterious skin condition.

According to China's People's Daily, Xiao Cui[e] first noticed the symptoms when he was in middle school, and his face has been getting saggier ever since, making him look a lifetime older than he really is.

Doctors in China still have yet to figure out Xiao Cui's condition, let alone finding a way to cure him. The 18-year-old student said he has no option but to accept his condition and just try to look on the bright side of life.

Luckily, Xiao Cui's condition does not give negative effects on his health.

Xiao Cui isn't the only person who's suffering from his condition, Hu Juan[f], a 28 year old woman who looks like an grandma was diagnosed with an extremely rare connective tissue disorder known as Cutis Laxa[g], it's a group of rare connective tissue disorders in which the skin becomes inelastic and hangs loosely in folds. Also there was 30 year old Yuan Taiping[h], whose sagging skin made him look at least five decades older.

Xiao Cui said people sometimes poke fun at his looks and he admits he does get upset from that but he still tries to stay positive, especially having supports from his friends and family, even his teacher rates him highly.

Now Xiao Cui is currently studying hard to pass his exams and hopefully get accepted at Beijing University or Tsinghua University, two of the most prestigious learning institutions in China.
