Bronze Age: An era following the Red Copper Age in archaeology. Bronze is an alloy of copper and tin, which has a lower melting point and higher hardness than copper and is easy to cast. The earliest bronze age in the world was Mesopotamia and Egypt, which began in 3000 BC. China was a highly developed bronze age in Shang Dynasty (BC 1600- 1046). In the bronze age, the use of stone tools could not be ruled out. Some areas are at the end of primitive society, and some areas have entered slave society. China established a slave country in the Bronze Age, and its agriculture, handicrafts and written language were well developed.

Bahrain is a beautiful island country in the Persian Gulf with a land area of 660 square kilometers. Although the area is small, its tombs and cemeteries are rare all over the world.

Bahrain's well-known tomb forest, tomb sea, rows of hilly tombs, neatly stretching for dozens of miles, very spectacular. According to incomplete statistics, the number of tombs is not less than170,000, covering an area of more than 30 square kilometers, making it the largest ancient tomb group in the world. Archaeologists studied and analyzed 70 excavated tombs and concluded that these tombs have a long history, dating back to the bronze age of 3000 BC. For those who study world history, the discovery of these ancient tombs is of far-reaching significance and extremely important.

There are two kinds of ancient tombs in Bahrain, one is a double tomb, the other is a single tomb, and most of them are single tombs. The head of the tomb faces east, the foot faces west, and the door opens from west. There is a stone lintel opposite the door. The left and right walls are made of five layers of stone, the ground is covered with fine sand, and the coffin is covered with slate. All the deceased were lying on the right side, with their heads facing east, their legs arched, slightly bent forward, their arms extended forward and their palms facing their faces.

There are not many cases of double burial, and probably only leaders can enjoy this privilege. The double tomb is divided into two floors. The tomb is 4.6m high and 20m in diameter. The ground floor is made of stone. There are two windows on the right wall, but there are no windows on the upper floor.

Whether it is a single tomb or a double tomb, there are funerary objects in all tombs. Among them, the most are red glaze vases, round-bottomed straight-necked wide-flowered striped pottery pots, daggers, metal spears, ostrich eggshells and ornaments made of animal bones such as antelopes and sheep, and some have dog bones at the entrance to the tomb.

These ancient tombs take us back to the era of people in trouble. At that time, the prosperity of Bahrain and Kuwait's Faleka Island appeared before our eyes. At that time, China's silk and porcelain had reached here. In the 10 century, the Arab historian Mesoudi once described it in his masterpiece "Golden Ranch": "China's ship sailed directly to Weng Man (now Sultanate of Oman? Port Siraf on the Persian Gulf, Bahrain (Bahrain? Ports such as Pula and Basra. Ships in the above places also sail directly to China. " Among the unearthed cultural relics seen in Bahrain Museum today, there are hand-driven grinding plates, lamps and bowls, lanterns and ancient Chinese coins made in China. These antiquities witnessed the friendly exchanges between ancient China and Arab countries.
