What are the eight meanings contained in the poem "I came from three thousand miles away"? With the sadness of autumn, with my sorrow of a hundred years, I climbed this height alone?

It is sad to be a guest in another country;

Frequent visitors, two sorrows;

Wan Li is a guest, three sorrows;

When the bleak autumn, four people are sad;

A few years have passed, nothing has been achieved, and five are sad;

The death of relatives and friends is six sorrows;

It's sad to go to Deng alone;

It's sad to be sick.
