The Prototype Fragments of Zhizhen Old Man and Lu in Water Margin;

On that day, Elder Zhizhen said, "Shen Zhi, you can't stay here. I have a younger brother, who met the abbot of Suoguo Temple in Tokyo, and was called the Zen Master of Educated Youth. I'll throw this book to him with you and find a monk to do it. I came to see it in the evening and gave you four words, which you can use all your life and remember today's words. " Shen Zhi knelt down and said, "Cudgel is willing to listen." The elder said, "When you meet the forest, you will be rich, when you meet the mountains, you will prosper, and when you meet the water, you will stop." Lu listened to four sentences and made nine obeisances to the elders. Carrying a parcel, a purse, a belly bag and letters, I bid farewell to the elders and monks. I left Wutai Mountain and went to the blacksmith's partition inn to rest, waiting for the mord to quit the knife.
