The interpreter Cai Chan who had been sent by Shang Ning, the Zhong-shan king of the country of Ryukyu, came and advised: "Recently, the Japanese bandits of the various islands have manufactured over 500 warships and intend to take Ji-long Shan by force. We are concerned that they will then be able to make sudden attacks on and will bring harm to the Fu-jian seas. We are thus especially sending a despatch of advice. The Vice Censor-in-chief Huang Cheng-xuan, grand coordinator of Fu-jian advised of this, saying: "Ji-long lies close to our Eastern border, and is only a few geng by sea from guarded areas (汛地). If the Japanese obtain it, they will then take the various islands of the Eastern fan in order to secure their lair. Subsequently, they will be able to make use of cracks, engage in spying and act as they wish...." The memorial was sent to the Ministry of War.
