Every year, Y.E.S. organises a Halloween Night as a prime platform for new members to showcase their creativity and bond with each other. In the event, team leaders are chosen from volunteers to lead small teams, which consists of new Y.E.S. members, to design their horror room in our Haunted House. The goal of Halloween Night is to let participants and members have fun and enjoy the celebration. Aside from Haunted House, Halloween Night also offers other events such as mini-games, photo booths, and costume competitions.
