His successor, Prince Hă-yang, is known by his posthumous title Ye-jong Yang-do Tă-wang. He was so young at the time that his mother acted as regent. During the single year 1469 that this king reigned the Great Bell was brought into the city and hung at the central spot called Chong-no or “Bell Street.” He also made the law that the palace gates should never be opened at night unless the one so ordering showed the royal signet or token, called the _su-gŭl_. This was a round piece of ivory half an inch thick and three inches in diameter with the word _sun-jun_ on one side and the king’s private mark on the other. To it are appended straps of deer skin and it is used when the king wishes to accredit a man to a certain work. The mere showing of this is accepted as the royal command. It is commonly called also the _pyo-sin_ “The Sign to be Believed.” This reign saw the division of the city into north, east, south, west and central districts. It also saw the promulgation of the Kyŭng-guk Tă-jŭn or “The Great Laws for Governing the Country.” The system had been inaugurated at the beginning of the dynasty but now for the first time it was definitely adopted and written out in full for the guidance of the official classes. It dealt with the minute divisions of communities, each having an overseer. This same year 1469 the young king died and his mother calling the Ministers together, nominated to the throne Prince Cha-san the cousin of the deceased king. As he was only thirteen years old the Queen Mother acted as regent during the first years of his reign. His posthumous title is Sŭng-jong Kang-jŭng Tă-wang. Under the regency of the Queen Mother the first act was the abrogation of the law requiring the people to wear the _ho-pă_ or wooden identification tag, which King T‘ă-jong had promulgated. It had become a mere matter of form and was found quite useless for the purpose intended, namely a preventative against the evasion of the taxes. This reign was marked by increased activity in the field of foreign relations. First an envoy came from Quelpart with a gift of pearls. Another came from the town of Ku-ju Si-so in the province of Kwan-sŭ (Japan) and still another, Chöng Sŭng-hong from the town of Wŭn-jung on the islands of Tsushima. One embassy from the Liu Kiu Islands came with a gift of monkeys. The Japanese on the island of Sal-ma sent an envoy who presented gifts of red pepper, incense and white silk. He asked for Buddhist books but was refused. Envoys came also from the northern tribes swearing allegiance to Cho-săn.
