While banners, large and small, vertical and horizontal, have been used throughout Hong Kong since as early as 1967, and most frequently during the annual Tienanmen Square Massacre march and vigil since 1989, it was the Umbrella Movement of 2014 marked the beginning of the uniquely Hong Kong hill-top vertical protest banners movement. A group of rock climbing activists decided to unfurl a 30-meter vertical protest banner on Lion Rock and document their descent on YouTube. At the time, even some Hong Kong citizens thought it was a joke. The yellow fabric echoed the iconic yellow helmet in the Umbrella Movement. Since then, many more hill-top banners have shown up throughout Hong Kong, and the messages to the government also become increasing harsh as Hong Kong authorities and Chinese government continue to crack down on dissents.
