The bronze of the Shang Dynasty weighed 832 kilograms and was an pouring molding, how could the bronze be so delicate, the curve was so smooth and perfect; later people restored a method of pouring bronze in the Shang Dynasty at that time called the lost wax method;
The model is made of wax and then applied to the wax inside and outside the container and outside the fine clay can not be fine, so it is equal to the clay is very fine wax carved on the fine will also have small clay particles into it, so the clay shape becomes the same as the wax carving is just two sets tightly combined together, and then the thing is dried and then burned to become a pottery; once the wax inside is burned, the wax will completely flow out to leave the appearance of such a container, and then pour in bronze juice, and the appearance that comes out is the Siyang wind called the lost wax method ，
This is now people speculate, whether it is done or not we really don't know, but look at the delicate and rounded pattern, the level of craftsmanship at that time must be very high, the Shang Dynasty is mysterious and powerful is to think that he is a landlocked country;
He seems to have the ability to sail the ocean, now the Shang Dynasty is excavated in the tomb a lot of sea shells are deep sea shells; the Shang Dynasty shell is a kind of money, in ancient China, everything related to money with a shell word, such as: poor, lowly, reward, gift all with a shell, this is a lot of money-related things are with shells, in archaeology also found some from Malaysia sea turtles, from Xinjiang Hetian jade, feel that the Shang Dynasty at that time the transportation capacity has been possible to overseas far away, Land can reach places like Xinjiang.
