Hong Kong police show their new goose step marching style on the National Security Education Day at a police school in Hong Kong Thursday, April 15, 2021. Authorities in Hong Kong are marking the day with a police college open house, where police personnel demonstrated the Chinese military's "goose step" march, replacing British-style foot drills. The "goose step" march is one in which troops swing their legs off the ground in unison, keeping each leg straight. (AP Photo/Vincent Yu)
