The Manchus were still fretful. A letter came post haste from the north saying, “We have now sent back many captives and you agreed to pay for the rest, but when they got across the border and were lost to us we never saw the money. Not a year has passed since the treaty was ratified and yet you break it with impunity. When the Chinese acted thus we retaliated by seizing twenty-four of their districts. Now you must send those men straight back to us.” Among all the courtiers there was but one dissenting voice, that of Chang Yu, who said, “The government is for the people and if it gives up any of the people thus, from that hour it ceases to be a government. Sooner should we let the Manchus destroy the government outright than comply with such a demand.” This carried the day, and an envoy was sent north bearing a present of a magnificent sword, 300 pounds of ginseng, seventy sable skins, but only five of the men demanded. The Manchus were highly pleased and forgave all that had been done to displease them. The Japanese hearing of this again sent an envoy saying, “Those Manchus are a bold lot. They have made a treaty with you but they do not treat you well. Just say the word and we will come and whip them for you.” This frightened the king and he wanted to forward the message to the Manchus but Kim Sin-guk said, “If you do that you will get the Manchus and the Japanese to fighting each other on Korean soil and we will be the little fish between two whales.” This argument carried the day. In the year 1629 the king established a naval station on Kyo-dong Island and placed there an admiral to guard that island and Kang-wha from attack from the seaward side. This was with the expectation that the court might again find it necessary to seek asylum on the island of Kang-wha.
