May you travel all over the mountains and rivers without being contaminated by years. What do you mean?

May you travel all over the mountains and rivers without being contaminated by the dust of the years, which means that you have experienced many people and many things, and when you see them again, you can still retain the childlike innocence of all young people. May you travel all over the mountains and rivers, free from the dust of years. This means that you hope that when you come back, you will not be freed from the dust of the years. It also means that you are expecting the best. I hope you will keep some pure thoughts and keep your love for everything in your future journey. It will never leave the dust of the years, and it is also the best blessing.
