"When you meet a forest, you will get rich when you meet a mountain, prosper when you meet water, and stop when you meet a river." This was left to him by his master, Elder Zhizhen, before Lu went to Sokokuji in Tokyo. It was these four sentences that hinted at Lu's life.

From the fifth time when Lu Zhishen left Wutai Mountain, Elder Zhizhen gave Lu Zhishen the third son.

Extended information:

Allusions: After Lu Zhishen's wild pig forest saved Lin Chong, he offended Gao Qiu, and Lu Zhishen set fire to the vegetable garden. Since then, he has lived in rivers and lakes and embarked on a unique road of no return.

Get rich when you meet the mountain: Lu Zhishen, Yang Zhi, a blue-faced beast, and Cao Zheng, a knife-wielding ghost, managed to seize Erlong Mountain as the king, and Lu Zhishen became the master of the cottage. Later, Wu Song, Shien, Zhang Qing and Sun Erniang all became outlaws, and the strength of Erlong Mountain gradually became stronger.

Being rich when encountering a mountain refers to Erlong Mountain. As a leader in Erlong Mountain, Lu Zhishen is rich in financial resources and power, especially with many like-minded brothers around him, which is naturally very satisfying.

Prosperity in the face of water: Later, because the imperial court wanted to wipe out the three mountains, including Erlong Mountain, the three mountains and Liangshan joined forces against the imperial government. Later, all three mountains belonged to Liangshan, and Lu Zhishen joined Liangshan. When Lu Zhishen was in the water margin, he repeatedly made meritorious military service and fought bravely. When Liangshan ranked first, Lu Zhishen ranked thirteenth, ranking first among all infantry troops.

Later, the Liangshan hero was enlisted by the imperial court, and Lu Zhishen also went into battle to kill the enemy. He also captured Fang La alive and made great contributions. "Water", which thrives on water, refers to Liangshan, Shui Bo. After joining Liangshan, Lu Zhishen began to truly realize his own value, doing justice for heaven, killing the rich and helping the poor, punishing evil and promoting good.

Stop when encountering a river: Some people will think of Song Jiang, probably because Song Jiang insisted on wooing, which ruined the lives of many Liangshan brothers and chilled their hearts, so he said "stop when encountering a river". This "river" refers to the Qiantang River. After the conquest of Fang La, Lu Zhishen refused to accept the imperial reward and became a monk at Liuhe Temple in Hangzhou.

Elder Zhizhen also gave him four other words: "Catch in summer, hold on to wax, listen to the tide, and be silent when you see the letter." Xiahou Cheng and Fang La were captured alive before Lu Zhishen's first two sentences, and then Lu Zhishen understood the meaning and died shortly after hearing the tide news of Qiantang River.
