Bronze is also the representative of ancient Chinese material culture. It appeared at the end of the Neolithic period and reached a peak in the Shang and Zhou dynasties. The patterns on the bronze ware are diverse, representing the highest level of early artistic attainments. The inscriptions on bronze wares are one of the main carriers of early Chinese writing. Appreciating it will help to understand the development of Chinese writing and improve the level of appreciation of calligraphy. The casting technology of bronze ware represents the highest scientific and technological level in ancient China, and the knowledge summed up by people in the mining, smelting and casting of bronze has been directly pushed to the arrival of the Iron Age in China. Among the numerous bronze wares in various periods, there are also some fine and heavy wares. The introduction of their patterns and appreciation of their shapes will help us to strengthen our understanding of Chinese bronzes and traditional Chinese culture. Tin carving is a traditional tin art widely popular among Chinese folk. Tin has the advantages of non-toxic, stainless, moisture-proof, acid and alkali resistance, soft texture, low melting point and easy to process. Traditional tin work is mainly used to manufacture daily necessities. The tin making process is a self-contained system, mainly including melting, casting, modeling, cutting, scraping, welding, polishing, decoration, carving and other processes and techniques. During production, the shape of the utensils is constructed according to practical functions. The finished tin ware is rich in shape and exquisite in decoration, which fully reflects the ingenuity of the designer. In 2008, tin carving was approved by the State Council of the People's Republic of China to be included in the second batch of national intangible cultural heritage list。
