On January 23, 2017, American Intercon Institute System conducted an open field study for Kid 5A, Kid 5B and Kid 5D students. All the participating students went to Kids City, which is situated in the lee of the looming bulk of Gold Tower 42. Kids City is an indoor edutainment center which provides all the students with the entertaining and educative activities. In terms of entertainment, there were fun activities such as a climbing wall, and ice skating, and laser tag. Therefore, we strongly believe that the field visit is an ideal opportunity for students to better understand the outside world and outdoor-class learning.
