Yamatokoku is one of the ancient states of Japan, also written as Yamataikoku.

He said, 'If you want to shoot a man, first shoot his horse,' and began to solve the smaller problems first.

This ancient proverb, 'know the other side and yourself, and you will not be in danger in a hundred battles', teaches us the importance of understanding ourselves and others.

The proverb 'If you want to shoot the general, first shoot his horse' means that to achieve a big goal, you should start with small steps.

He quoted the proverb 'Once a word leaves your mouth, you cannot chase it back even with the swiftest horse' to teach me to choose my words carefully.
