What's the meaning behind the name "Wutongyue"?

Sycamore refers to sycamore tree. In ancient times, it was said that phoenix tree was a male tree and phoenix tree was a female tree. Phoenix tree grew up with death, with tall and straight branches and deep roots. In the poet's pen, it became a symbol of faithful love.

The moon refers to the shade of trees, which means that the elders take care of the younger generation or ancestors and protect their children and grandchildren.

That's probably what it means.
