Rulers, whether the Emperor or vassals, faced south in the exercise of their sovereign powers. Thus, when the Duke of Chou, after the death of his brother the Martial King, acted as Regent pending the minority of the Martial King's son, his own nephew, he faced south; but he faced north once more when he resumed his status of subject. It has already been mentioned, in Chapter XX., that in 640 B.C. the state of Lu made the south gate of the Lu capital the Law Gate, because it was by the south gates that all rulers' commands emanated. In 546 a counsellor of Ts'u explained to the king how, since Tsin influence had predominated in the orthodox state of CHÊNG, this last had ceased to "face south towards its former protector." Thus, though the Emperor faces south towards the sun, and his subjects in turn face north in his honour, those subjects face their other protector in whatever direction he may lie, supposing the Emperor's protection to be inadequate. It is evidently the same principle as "bowing towards the east," and "turning towards Mecca," both of which formalities must be modified according to place. In 315 B.C., when Yen (the Peking plain) had become one of the six independent kingdoms, a usurper (to whom the King of Yen had foolishly committed full powers) "turned south" to perform acts of sovereignty in the king's name. In 700 B.C., in the orthodox state of Wei, we hear of "princes of the left and right," which is explained to mean "sons of mothers whose official place is left or right of the principal spouse." Right used to be more honourable than left in China, but left now takes precedence of right. Thus the provinces of Shan Tung and Shan Si are also called "Left of the Mountains" and "Right of the Mountains," because the Emperor faces south. Notwithstanding, the ancient phraseology sometimes survives; for instance, "stands right of him" means "is better than he is," and "to left him" means "to prove him wrong or worse." All _yamêns_ in China face south; there are rare exceptions, usually owing to building difficulties. Once, in the province of Kwei Chou, I was officially invited by the mandarin to take my seat on his right instead of on his left, because, as he explained, his _yamên_ door did not face south, but _west_; and, he added, it was more honourable for me, as an official guest, to sit north, facing west, than to sit south, facing west. In Canton, the Viceroy used out of courtesy to sit south, facing north, and make his own interpreter sit north, facing south; the consul sat east, facing west, and the consul's interpreter sat west, facing east. But the consul could not have presumed to occupy the north seat thus given to an inferior on the principle of de _minimis_ non _curat lex_; nor was the Viceroy willing to assert his "command" to a guest. In 436 the armies of Yiieh marching north through Ho Nan called the Chinese places lying to their west the "left" towns; but that
