Which festival can be associated Moon cake?

From a wine pot amidst the flowers,
I drink alone without partners.
simo mid-autumn festival
To invite the moon I raise my cup.
We're three, as my shadow shows up.
Alas, the moon doesn't drink.
My shadow follows but doesn't think.
Still for now I have these friends,
To cheer me up until the spring ends.
I sing; the moon wanders.
I dance; the shadow scatters.
Awake, together we have fun.
Drunk, separately we're gone.
Let's be boon companions forever,
pledging,in heaven, we'll be together.
