'Panda Knight' leaves his mark over 8 years

When President Xi Jinping made a speech at Nazarbayev University in Astana, Kazakhstan, in September 2013, he mentioned a young Kazakh man who was famous for donating blood in China.

Tulenov Ruslan, a postgraduate student at Beijing Science and Technology University, was praised by the president as "part of a Sino-Kazakhstan Friendship Epic".

In the past eight years, he donated more than 5,000 milliliters of blood in China, an amount that exceeds the average adult's blood volume.
