This week was a dream-come-true for military watchers. August 1 marked the 90th birth anniversary of the People's Liberation Army (PLA). Various events were held across the country, including a parade at an exercise field in Inner Mongolia for the first time in four decades. But the past seven days saw more than just fighter jets taking to the blue skies. Major storms delivered a double punch on the eastern provinces while other parts of the country sweltered under record heat. Here's the week's recap.
