The mastery of work is due to diligence but not to play, and success is achieved by thinking and ruined by casualness. (Han Yu, Tang Dynasty, "Jin Xue Jie") If the mountain is not high, there will be immortals, and if the water is not deep, if there are dragons, there will be spirit. (Tang Dynasty Liu Yuxi's "Inscription on the Humble Room") Observe the law and uprightness, and you will be like an autumn mountain

——Tang Dynasty Liu Yuxi's "Sikong Xigong Divine Monument"

Be greedy and greedy
