Haven't you heard the classic slogan of Yanghe Blue? Yanghelan's classic slogan is "The sea is the widest in the world, the sky is higher than the sea, and people's feelings are wider than the sky".

The sea is the widest in the world, the sky is higher than the sea, and people's feelings are wider than the sky. Chinese blue.
