Kneel down and beg to translate a passage in the thirteen general comments of Huai Nan Zi Juan.

In ancient times, people lived in Zeguo, a water town, and dug holes on the cliffs along the river bank to live. In winter, they can't stand the attack of frost, snow and fog, and in summer, they can't stand the heat and mosquito bites. So the saints built houses for the people, with tiles on the top and eaves under them, to shelter the people from the wind and rain, keep out the cold and summer, and the people lived in peace from now on. Apollo began to make clothes, rubbing hemp rope and twisting hemp thread, and his fingers wrapped around clothes as rough as a net; Later, the loom was invented, which facilitated people to spin cloth and silk, and enabled people to keep out the cold. In ancient times, people sharpened stones as plows, sharpened clams as hoes and hoes, chopped firewood with wooden hook knives, and drew water with crocks. People are tired and earn less at this time. Later, I invented the thunder hoe to plow and sow, made an axe to cut wood, and drew water with orange sorghum, which made people relaxed and profitable.

In ancient times, rivers and deep valleys blocked traffic roads, making communication between people very inconvenient. So people hollowed out trees and pieced together boards to make boats and boats, so that people and products from all over the world can transport and exchange needed goods. Because people are tired after walking thousands of miles, they invented cars and dragged them by horses and cattle, so that people don't feel tired when they travel by car. Because wild animals and birds hurt people, they can't defend themselves, so people cast gold and iron into weapons and knives, so fierce animals will no longer hurt people. Therefore, when people are forced to face difficulties, they will be forced to find suitable solutions, and when they are troubled by disasters, they will invent defense devices. People use their intelligence to avoid harmful things and tend to favor beneficial things.
