"Going up the mountain to see Shang Lugen" is usually considered as the meaning of closing the mountain and washing hands. In this case, Shanlong represents people who have retired from Jianghu, while Shanglu represents people who are wandering Jianghu. This statement is usually related to the release of prisoners from prison, because these people need to re-enter society and start their lives again after serving their sentences.
But the meaning of tattoo is very personal and can be explained according to personal experience, beliefs and ideas. So when it comes to tattoos, everyone may have a different understanding. If you have any questions or concerns about tattoos, you'd better consult a professional tattoo artist or psychological counselor to understand its possible significance and influence.
