More than 180 veterans, who are in their 60s, gather before the 90th anniversary of the founding of the People's Liberation Army (PLA) and climb Funiu Mountain in Luoyang, Central China's Henan province, July 31, 2017. They climbed the over 2,000-meter-high peak where they raised the national flag, dined together and held a singing contest, just like the troops do. The PLA birthday falls on August 1. [Photo/VCG]
