Form and Meaning of the Wood-Grain of the Dou in Dougong Bracket-Analysis of the Crosscut Dou in the Main Hall of Baoguo Temple
The main hall of Baoguo Temple in Ningbo of Zhejiang was built in the Northern Song dynasty. Based on a thorough survey，the author finds out that all the Dou (the square block in the Dougong bracket system of Chinese wooden building) in this hall are crosscut——their front surfaces are all transverse sections，thus the annual rings of the wood can be seen from the front view. By contrast，all the Dou in the wooden buildings in northern China are cut in the direction of the wood-grain during the Tang through Song dynasties. These two different techniques reflect characteristics of two traditions of workmen from different areas. The tradition of crosscut Dou not only passed down in wooden buildings of the Song through Yuan dynasties in the Jiangnan area，but also was transmitted to other countries of eastern Asia，appearing in the architecture of Japan and Korea.

Excavation Report of the Eastern Gate No.1 of the City Site of Erligang Culture in Wangjinglou，Xinzheng，Henan
Zhengzhou Municipal Institute of Cultural Relics and Archaeology
From September of 2010 to April of 2011，the Zhengzhou Municipal Institute of Cultural Relics and Archaeology uncovered a city site of the Erlitou Culture and a city site of the Erligang Culture at the Wangjinglou site in Xinzheng City. In the city site of the Erligang Culture，3 city gates were found. One of the two eastern gates （dubbed No. 1）was well -preserved，having an unusual structure sug- gesting the early emergence of the wengcheng-type barbican，which is strongly suggestive of military defense. Archaeologists suggest that this city site was possibly one of the important military settlements in the southern part of the Shang City in Zhengzhou. The excavation of the Eastern Gate No. 1 provides important materials to the study of the structure of city gates of the Shang dynasty and the construction of early cities.
