Ruslan Tulenov is a young man from Kazakhstan who is currently living and working in China's Hainan Province. He went to study at Hainan University in 2009 and donated blood twice a year. In 2013, to his astonishment, he was mentioned by President Xi Jinping in a speech at Nazarbayev University in Astana. The Chinese president praised the young Kazakh for making regular blood donations that were saving Chinese lives. It later came as a pleasant surprise to Ruslan when, during a visit to Hainan in 2022, President Xi revealed that he still remembered him.
