'Mosquito house' refers to idle public facilities in Taiwan. Since 2010, artist Yao Juichung has been leading members of LSD (Lost Society Document) to work on the 'Mirage' project, surveying the phenomena of 'mosquito house' all around Taiwan. The first-hand information of LSD members and their on-spot documentation point to some common factors behind the idleness, including the loss of planned function due to the change in time and space, and the mismatch of public demand and public policies. Some are also born from the corrupted election and bidding systems.

Not only does the investigation of 'mosquito house' raise the hidden concerns of government's policy, but also exposes the deformed value of the country, of which hard ware development is overly stressed and construction is falsely equated to economic development.
