On March 1, 2014, eight knife-wielding Xinjiang terrorists unleashed deadly attacks on unsuspecting passengers at Kunming Railway Station in Southwest China's Yunnan province. The assailants killed 31 civilians and injured over 140. "Xinjiang Under Blue Skies" is a song jointly created by six Uygur and Han musicians in the aftermath of the attack. Chen Ruijun, who wrote the song, said people from other regions in China began perceiving Xinjiang and its people in a negative light after the attack. Changing people's perception of Xinjiang through the power of music became the biggest motivation for Chen and his fellow musicians. The song took over half a year to produce – much longer than other pieces. "At a time when attacks of different scales were taking place periodically in Xinjiang, people were anxious and depressed," said Chen. "Under these circumstances, we wanted to create a song that helps people face the confusion and the hardship, and helps open their hearts and minds." On Friday, April 2, CGTN will present "The War in the Shadows," the last episode of a tetralogy chronicling the fight against terrorism in Northwest China's Xinjiang Uygur autonomous region. It portrays the plight of Xinjiang residents living through the aftermath of terrorism in the region, unveiling the inside stories behind decades of struggles.
