The plan attempts to praise the most beautiful “sails” on the canal to send our compliments to the city. The building is designed in two-tower type, one of the towers flies briskly and the other converges steadily. Both of the towers are interactive to each other through a free-developed public space, both are blanking gradually when looking upwards, and are open to the city to the ground. The axis between double towers is exact the axle of the surrounding cities, when the sunshine penetrates through the gap of the two buildings, it enlightens the city and maps an exciting and prosperous vision of the city.
