Excavation of Huangzhong Village Site
　　From December 1995 to April 1996, Chengdu Archeology Institute of Cultural Relics conducted exploration and archaeological excavations of Huangzhong District in the Huangzhong Village. The exploration covers an area of about 700 square meters and a large number of pottery were unearthed, of which cups with pointed bottom and the long-necked tank are the representative ones. Discoveries from this site can date back to the late Shang Dynasty to the early Western Zhou Dynasty. The Huangzhong Village, therefore, is a typical site of cultural relics of the Shang&Zhou period.
　　From June 1999 to April 2000, a large-scale archaeological excavation was carried out in Sanhe Garden of the village with the total exploration area of 2026 square meters. This area particularly abounds in archaeological sites of great cultural heritage. Totally 17 sites of Housing Blocks, 17 sites of Kilns, more than 300 hoards and 13 burial sites were found.
　　From July to Sepember 2000, another site Jindu Gardon of the Huang Zhong village was excavated. The excavations expanded an area of about 500 square meters but cultural heritage here is relatively less and only a small number of Kilns, hoards and burials relics were unearthed together with limited numbers of pottery. All these relics are supposed to be existing in the late Shang Dynasty to the early Western Zhou Dynasty.
　　The three explorations have led archaeologists to decide that the Huangzhong Village should be one of the typical cultural ruins of the 12-bridge Relics. The whole district amounts to about 1 square kilometer. Roughly It had coincided the period of the late Shang Dynasty to the early Western Zhou Dynasty. All signs indicate that the site may be part of the relatively high-grade large palace architecture of Jinsha ruins.

Archaeological excavations of the northeast part of the Meiyuan Site
　　The Meiyuan Site is located to south side of the Modi River and west of Qingyang Road with a land area of about 220,000 square meters. It has been confirmed through exploration that the area of cultural heritage reaches about 80,000 square meters. From February to June 2001, Chengdu Institute of Cultural Relics and Archeology conducted archaeological excavations of the Regional Center. A total of 145 exploration sites of 3,625 square meters have beendetermined. So far, the excavation has come to the 8th layer. From the relics unearthed, the 5th layer could be traced into the Spring and Autumn Period, and the 6th and 7th layers to the Western Zhou Dynasty. From the stratigraphic section mechanically excavated, stratum of the region is about 4.5 meterst thick, and cultural heritage accumulation can be divided into at least 16 layers. More than 700 precious pieces made of jade, bronze, gold and fortune-telling tortoise-shells were unearthed from the Western Zhou Dynasty layer. Besides, a large number of pottery and ivory were also unearthed. Three kinds of remains of extraordinary significance had been found in the region. The first is the ivory pit where several hundred ivory piling up with some jades and bronzes. The second covers about 300 square meters and mainly of half-finished stone pieces and stone tablets which were piled up in inclination into layers. And in the last pit, which covers about 300 square meters, concentrated pieces of wild boar fangs, deer antlers, ivory and pretty stones. All of the three pits of relics may have to do with religious activities.

Archaeological excavations of the northeast part of the Lanyuan Site
　　This site is situated in central and southern Jinsha ruins with the cultural heritage area of about 20,000 square meters. From July 2001 to January 2002, Chengdu Institute of Cultural Relics and Archeology conducted a large scale archaeological excavations of the cultural heritage area. A total of 512 exploration sites of 12,800square meters have been determined. A large number of architectural ruins, pottery soil, rows of kilns, more than 400 hoards, over 80 tombs and 1 pottery kiln were discovered and thousands of potsherds and pottery, and a small number of jade, bronze, gold pieces and so on were unearthed. Remains of this site can be retraced to the late Shang dynasty. All signs indicate that cultural heritage district in the Lanyuan Site might be living areas and small burial area.

Archaeological excavations of the Sports Park
　　The Sports Park arrives at the Modi River in the north, the Lanyuan Site in the south and the noth part of the Meiyuan Site in the east with the cultural heritage area of about 36,000 square meters. From October to November 2000, Chengdu Institute of Cultural Relics and Archeology conducted the trial excavation of two locations within the region which covers an area of 162 square meters. Housing blocks, pottery soil and 13 graves were unearthed. All of the 13 graves concentrated in the 81-square-meter area which have been tentatively confirmed as the second funeral. Burial objects have been found in three of them including jade and pottery devices. According to the pottery burials, the tombs mightbe built in the early period of Western Zhou Dynasty. Considered the housing sites and the broken cultural layer, the burial site might be originally a living area which was used for burial only after being abandoned.
