my favorite 4 character proverbs

竜頭蛇尾 - Literally meaning "dragon head snake tail." This describes someone who starts something off with much enthusiasm, rigor, and energy but fails to "finish the race." Pretty much one has pooped out.

山戦水戦 - One has battled the mountains and rivers. Thus, one has seen and experienced the world.

道成肉身 - Truth changes into flesh and body. In biblical terms, the Word became Flesh.
