天地皆入梦江山尽相思
[tiān dì jiē rù mèng jiāng shān jĭn xiāng sī]
Literal translation would be 'All of heaven and earth falls into dreams; rivers and mountains fill with longing.' It’s a beautifully romantic way of saying that everything around turns dreamy, and the natural world echoes one’s unspoken lovesickness and yearning.
