What are the names, pictures and introductions of ancient cultural relics in China?

Bronze sword: Bronze sword began in Shang Dynasty. At that time, its leaves were generally short, shaped like willow leaves, and its production was relatively rough. After the late Spring and Autumn Period, the production of bronze swords reached maturity, and the story of "Gou Jian, the King of Yue" happened in this period. At this time, bronze swords are generally lengthened to 50 or 60 centimeters. A bronze sword is mainly composed of the body and the handle, and the so-called "handle" is the handle. There is also a raised partition between the hilt and the body, which is called "grid". The more exquisite bronze sword has some decorations on the "lattice" to show the identity and status of the user. These decorations are usually made of jade, so this kind of sword is also called "Jade Sword". After the Eastern Han Dynasty, bronze weapons were completely replaced by iron weapons, and bronze swords withdrew from the historical stage. Bronze swords were often used in ancient wars in China. Generally, it is made of copper-tin alloy by melting.

Looking back on the development of bronze swords in the Central Plains, the body of the sword is getting longer and longer. At first, the sword was only twenty or thirty centimeters long; In the Spring and Autumn Period and the Warring States Period, the length generally reached about 50 ~ 60 cm; In the late Warring States period, some swords exceeded 70 cm, and the longest reached 75 cm or 76 cm. In the Qin Dynasty, the length of Jian Qin in Guanzhong reached a new level, exceeding 80 cm, and the longest reached nearly 95 cm. The history of the creation and development of bronze swords in China can be traced back to the Shang and Zhou Dynasties. The primitive society began to enter the slave society and reached its peak, and then it continued until the Qin and Han Dynasties.

After the iron sword appeared, the bronze sword gradually disappeared. Through field archaeological excavations, bronze weapons including bronze swords have been unearthed all over the country, which can be said to be endless and colorful. Especially in recent years, the discovery of the sword of Fu Cha, the king of Wu, and the sword of Gou Jian, the king of Yue, shocked China and foreign countries and became rare treasures.
