The ports of the old canals were built in the Haian district. Passengers boarded and disembarked whilst goods were transported here after inspection and documentation. The district was similar to a customs agency. For this piece the artist used bamboo battens to make a 3D cloud, which can engage in dialogues with people. People can take photos and enter personal messages into the cloud, and check-in at this place, becoming a part of Tainan’s tourist spots.
