CHINESE DIAMOND KNOT
Location: Design Period: Critic: Cooperator:
Chinese Character Museum The prototype of this museum starts from the study of traditional Chinese architectural spaces and attention to the existing architectural culture surrounding. Chinese characters initiate from diamond knots, which can be traced to thousands of years ago. This museum is like one diamond knot formed by two twisted pedestrian flows and spaces.
Hangzhou, China Winter 2012 Jun Ren Shu Yang
Historical development of Chinese characters N
Tracing back to ancient times of China, the first script is to keep records by tying knots. Then "Chinese seven fonts" including carapace-bone-script, bronze script, small seal script, official script, regular script, running script, cursive style were invented. Notes on tying knots for recording
Sketch
Site Plan
Book of Change (one of the Five Classics of China):"Peoplle tied knots to keep records in the ancient times, and then wise men invent writing to substitute that."
Diamond Knot: One of the simplest Chinese knots, which was used to keep records in the ancient times and is used as a tailsman now.

Most buildings surrounding this site belong to the kind of Hui Style Architecture, which is one of the most important genres in Chinese architectural history. They mostly have gray tiles, pitched roof and white walls with square windows. This kind of vernacular dwelling is a collection of multi-courtyard-style buildings. Hui Style Architecture is popular in Jiangxi and Zhejiang provinces now.

ALONG THE CRACK Wenchuan Earthquake Museum On May 12, 2008, the most severe earthquake since China was established happened, which resulted in the death of thousands of people.
Location: Design Period: Critic: Contribution:
Chengdu, China Spring 2011 Jun Ren All
Along the crack created in the design, people will see the ruins that remained after the earthquake under the slope roofs. Crack is the symbol of the disaster. But at night, the crack full of light will bring hope and console the pain of the city. When people walk along the crack and recall the disaster and victims, when people sit on the roofs looking far away to think of life's value, the victim will gain eternal life in the country's memory.

Guangzhou Nansha New District Jiaomen River Center Competition Nansha New District in Guangzhou is the geographical center of the Pearl River Delta and the key development area to connect Hong Kong and Macao. The project is located in the city center. Here is the point where local culture and global culture meet.
Cooperator:
Nansha, China Summer 2013 U11, CAG whole competition period Limiao (Project manager), Jing Sun
Globalization and Localization Unique spatial complexity is created by the combination of modern urban interface and traditional Guangzhou space. Time and space Development is the main feature of the new district. Time is considered time the fourth dimension. Bridge Located in the junction point, the circular bridge is the knot of the two main axes of Nansha. The bridge is the combination of a pedestrian bridge and a motor bridge to meet the requirement of the clients.
