What is the meaning of this poem by Li Po?

Question

I take my wine jug out among the flowers
to drink alone, without friends.

I raise my cup to entice the moon.
That, and my shadow, makes us three.

But the moon doesn’t drink,
and my shadow silently follows.

I will travel with moon and shadow,
happy to the end of spring.

When I sing, the moon dances.
When I dance, my shadow dances, too.

We share life’s joys when sober.
Drunk, each goes a separate way.

Constant friends, although we wander,
we’ll meet again in the Milky Way.

Answer 1

Li po was lonely.. yet she feel adequate with the things she has..

"We share life’s joys when sober.
Drunk, each goes a separate way."
it could be that : when we have difficulties, true friends will always be there with you.. having them around is one of the joy in life..
however, when you're drunk @ happy, ( of celebrating something ), friends will continue with their own business..

in other words, i might say , friends will say something like this:
" if you cry, i'll cry for you too.. if you're happy, you won;t need me that much..so let me continue my journey of life."

"Constant friends, although we wander,
we’ll meet again in the Milky Way."
: but they ( true friends ) are always there for her.. or at the very least, praying for her

this is just my point of view..
it's just the way i feel when i read it..
and i like this poem too..
