What does "Jun Xi" mean?

Xi, a Chinese character in China, is an auxiliary word in classical Chinese, which is equivalent to modern "ah" or "ya". There is a famous poem that contains this meaning.

There are trees on the mountain, but there are branches on the tree, which makes you happy.

There are trees on the mountain and trees have branches. I like you in my heart, but you don't know it.
