Who signed this word?

The handwriting is rough and white, which looks casual and fake. The text of the work should be "reading and writing like a god"; Inscriptions "Du Fu sentenced Wang Zhenxing and Mo Zheng to trial" and "Sun You (? ) year "; The seal is Sun's. Wang Zhenxing-meticulous painter, good at painting tigers; Sun Younian, a painter, is a disciple of Wang Tianchi, a disciple of Qi Baishi, who is good at painting shrimp. His works are refined: the domestic market price is 3000-6000 RMB per square foot, and the international market price is 700- 1000 USD per square foot. But I can't tell whether your work is true or not.
