During the winter vacation, teachers and students from the archeology department of the School of History and Culture at Shandong University (SDU) carried out several practical trainings in such areas as field excavation, data collection and archaeological investigation at the Jiaojia relics site in Jinan's Zhangqiu district in Shandong province.

Students in the field excavation team completed excavation, measurement, drawing, photographing and recording independently. After cleaning and collecting relics, they mastered the basic excavation techniques and improved their practical skills.

According to the situation of the relics unearthed at the Jiaojia site, teachers and students made a preliminary arrangement of the excavated materials this year. They checked the original records and collected all kinds of data records in the smallest accumulation unit to optimize the database and the field excavation geographic information. Based on the original data records, they selected specimens and restored various objects such as painted pottery and other relics which are hard to preserve.

In addition to excavation and data collection, teachers and students also conducted small-scale archaeological investigations on site.

The investigation consists of two categories: a region-based full-coverage survey and a site survey. The former is to systematically record the distribution of relics, and the latter is to understand the environmental characteristics and landscape of the site through a detailed investigation.

Through the investigation, students are able to gain an in-depth understanding of key information such as the scope of the site and its cultural connotations.
