The ancient native names for Wu and Yiieh, according to the clumsy Confucian way of writing them, were something like _Keu-ngu_ and _O-viet_ (see Chapter VII.); but it is quite hopeless to attempt reconstruction of the exact sounds intended then to be expressed by syllables which, in Chinese itself, have quite changed in power. The power of Yüeh was supreme after 473; its king was voted Protector by the federal princes, and in 472 he held a grand durbar at the "Lang-ya Terrace," which place is no longer exactly identifiable, but is probably nothing more than the German settlement at Kiao Chou; in 468 he transferred his capital thither, and it remained there for over a century, till 379: but his power, it seems, was almost purely maritime, and he never succeeded in obtaining a sure footing north of or even in the Hwai valley, the greater part of which he subsequently returned to Ts'u. It must be remembered that the Hwai then had a free course to the sea, and of a part of it, the now extinct Sui valley, the Yellow River took possession for several centuries up to 1851 A.D. He also returned to Sung the territory Wu had taken from her, and made over to Lu 100 _li_ square (30 miles) to the east of the River Sz; to understand this it must be remembered, at the cost of a little iteration, that Sung and Lu were the two chief powers of the middle and lower Sz valley, which is now entirely monopolized by the Grand Canal.
