Kaotsou began his reign by a public proclamation in favor of peace, and deploring the evils which follow in the train of war. He called upon his subjects to aid his efforts for their welfare by assisting in the execution of many works of public utility, among which roads and bridges occupied the foremost place. He removed his capital from Loyang in Honan to Singanfoo in Shensi, and as Singan was difficult of access in those days, he constructed a great highroad from the center of China to this somewhat remote spot on the western frontier. This road still exists, and has been described by several travelers in our time. It was constructed by the labor of one hundred thousand men through the most difficult country, crossing great mountain chains and broad rivers. The Chinese engineers employed on the making of this road, which has excited the admiration of all who have traversed it, first discovered and carried into execution the suspension bridge, which in Europe is quite a modern invention. One of these "flying bridges," as the Chinese called them, is one hundred and fifty yards across a valley five hundred feet below, and is still in use. At regular intervals along this road Kaotsou constructed rest-houses for travelers, and postal-stations for his couriers. No Chinese ruler has done anything more useful or remarkable than this admirable road from Loyang to Singanfoo. He embellished his new capital with many fine buildings, among which was a large palace, the grandeur of which was intended to correspond with the extent of his power. The reign of Kaotsou was, however, far from being one of uncheckered prosperity. Among his own subjects his popularity was great because he promoted commerce and improved the administration of justice. He also encouraged literature, and was the first ruler to recognize the claims of Confucius, at whose tomb he performed an elaborate ceremony. He thus acquired a reputation which induced the King of Nanhai--a state composed of the southern provinces of China, with its capital at or near the modern Canton--to tender his allegiance. But he was destined to receive many slights and injuries at the hands of a foreign enemy, who at this time began a course of active aggression that entailed serious consequences for both China and Europe.
