"Shui Diao Ge Tou·Going Back to Jinggangshan"

1965 Mao Zedong

Having long-standing ambitions, he went back to Jinggangshan. After traveling thousands of miles to find the old place, the old appearance has changed into a new one. There are singing and dancing birds everywhere, gurgling water, and the high road reaches the clouds. After crossing Huangyangjie, there is no need to look at dangerous places.

The wind and thunder are shaking, the flags are flying, it is the world. Thirty-eight years have passed in a blink of an eye. You can go up to the nine heavens to catch the moon, you can go down to the five oceans to catch turtles, and you can talk and laugh and return in triumph. Nothing is difficult in the world, as long as you are willing to climb.

Translation:

I have had great ambitions since I was a child, and today I climbed Jinggang Mountain again. I have traveled thousands of miles to look for this old land, but nowhere is it still half of its former appearance. There are new late spring scenes of orioles singing and swallows flying everywhere, as well as flowing water, and the wide winding mountain road goes straight into the clouds. After passing the Huangyangjie Pass, there are no dangers to be seen.

The wind and thunder are moving, the flags are fluttering, this is the world. Thirty-eight years have passed, like a snap of a finger. You can fly into the sky to pick up the moon, or you can dive into the ocean to catch fish or turtles, and sing triumphant songs to return the favor while talking and laughing. There is nothing difficult in the world, as long as you are determined to climb it.
