Introduction to the Wind Flag Stand: is the 846th Korean treasure. There is a pole stuck on the top of the stand and a piece of cloth tied to the pole. This is a tool used to measure the wind direction and speed. Because wind and rain were so important to agriculture, the royal family set up wind flags and rain gauges in each palace for accurate measurement. There is a Chinese watch next to the wind flag stand. Use this gorgeous watch to tell the time in the palace. Not only in palaces, but also in front of Jongno and Jongmyo Shrine, Hwapyo was installed for the common people.
