Introduction to Chongqing Science and Technology Museum: Chongqing Science and Technology Museum was completed and opened on September 9, 2009. Its appearance is made of stone and glass. The exterior wall stone uses a variety of overlapping colors to resemble a hard rock, which is a metaphor for "mountain"; the glass curtain wall, which accounts for 60% of the entire exterior wall and covers an area of nearly 10,000 square meters, is clear and transparent, a metaphor for "water". The sharp edges and corners of the stone and the transparency of the glass perfectly demonstrate the characteristics of Chongqing as a "landscape city".
