The _na_ of T’am-na is the same character. To the word Sil-la was added the word _Kuk_ or “kingdom” which put her in line with the other vassals of China. The Confucian code must have been making headway too, for in the following year the custom was adopted of assuming a mourning garb for three years upon the death of a parent. It was at this time that the influence of China upon Korea began to bear its legitimate fruit. Chinese religion, literature, government and art were beginning to mould the thought and life of the Korean people. Many Chinese words had been introduced into Korea before this time but the use of the Chinese character had not been general. In the mean time Ko-gu-ryŭ had been paying attention not so much to internal reforms as to external alliances. She sent to the Wei Emperor begging him to remit the revenue in gold and jade, as they were obtained, the one in Pu-yŭ, which she claimed the Mal-gal savages had seized, and the other in Sŭp-na which she averred the wicked Păk-je had feloniously taken. But she added “Of course all that Ko-gu-ryŭ has is yours”. The Emperor good-naturedly remitted the revenue but urged his vassal to continue the good work of subduing the wild tribes of the peninsula. It is said that in a single year Ko-gu-ryŭ sent three separate embassies to the Wei court. At the same time she was coquetting, _sub rosa_, with the new Liang power which had arisen in 502. In this Păk-je of course followed suite. We thus see that the three kingdoms spent their time in different ways; Sil-la in internal improvement, Păk-je in self-gratification and Ko-gu-ryŭ in strengthening her foreign relations. In the year 512 the kingdom of U-san was added to the crown of Sil-la. This was the little island of Dagelet, off the eastern coast of Korea, about opposite the prefecture of Kang-neung. How Sil-la happened to branch out in a policy of conquest we are not told, but having decided to do so she did it very neatly. The expedition was led by Gen. Yi Sa-bu. He ordered the construction of several lions with gaping mouths and enormous fangs. They were carved from wood. He placed one of these in the prow of each of the boats and when the little flotilla approached the shores of the island the natives were called upon to lay down their arms and surrender, or the lions would be set loose among them and would tear them to pieces. This, it is averred, brought the trembling islanders to their knees at once and Sil-la won a bloodless victory. This is among the most cherished traditions of the Korean people.
