What were the last four or eight words General Yue Fei spoke when he was force to sign a confession?

I visited General Yue Fei Temple in Hangzhou, and almost all the writings are in Chinese, and I was unable to read many many words in Chinese, so, I didn't understand much about what had been written there.

But, I was and am trying to understand what were the four or eight words General Yue Fei spoke when he was forced to sign a confession while he was in captivity.

What is the meaning of "Return River and Mountain to Me"?

What is the meaning of "Shine Day Shown Heart" on the plague of top of the temple door?

Please let me understand.

Thank You.
