The state of Qi was a neighbor of the State of Lu. Lu mu not only didn't go to ally with the state of Qi, but sent his prince and princess to Jin state and Chu state which were far away from the State of Lu to be an official. He thought that when the state of Lu was in trouble, get assistance from Jin and Chu.
A minister named Li Niu said to Lu Mugong, "If there is a big fire in the capital of Lu, someone will say to you, 'There is the most water in the sea, send someone to the seaside to carry water to put out the fire', does the King think it can be done ?"
"No, no," Lu Mugong said, "when the sea water arrives, the capital has already been burnt to ashes ."
"Yes," Li Niu said, "This is called 'distant water can't save the distant Fire'. Although Jin and Chu are very prosperous now, they are far away from LU. If Lu is in trouble, will be like yuan shui jiu bu le jin huo. While Qi and Lu are adjacent to each other, it is really dangerous to make friends with Qi state !"
