I just bought a calligraphy work by Ye Nong for 100. How much is it worth?

I went there some time ago and bought a pair of words. I spent 400 yuan. Whether these things are worth it or not depends on whether you like them or not. I went back to get the words and read them with several people. They all say it's ok and skillful. If you want to wait for this appreciation, it's probably over. As long as you like it. .
