The text of the cursive calligraphy hall in the photo is:
The grass will not die even if the stone presses it, and the flowers will bloom even if the cold hits it.
In the spring, the stones are removed, and the flowers and trees grow like spring.
The signature is:
Gongshu writes a poem by Dong Biwu.
The last two words in the signature should be the author's name, but I didn't recognize it, and the seal couldn't be seen clearly.
Hope this helps.
