Why did the tang dynasty face difficulties toward the end of its region?

Y my fav topic. Alright okay, so the Tang Dynastyhad like so much problems but not so many. So there’s a peasant uprising, and the power of eunuchs, and the power of governors, so the internal conflict grows as it grows, the power of governors and the eunuchs grew until it was taken over by Zhu Wen, of course a military governor. Hope this helps :))

Interpreting the results of his experiment : )
