Wandering in Wan Li is bitter, who can talk together? Where are the people holding hands in the long world of mortals? what's the meaning

Personal understanding, for reference only, I am wandering around alone, like a boat without sails, drifting aimlessly. Who can understand the bitterness of Wan Li's wandering and loneliness, and who can listen to my bitterness? Rolling the world of mortals, long life, who can accompany me? It mainly tells the story of the hard journey of life. Where is the person who can hold your hand?
