Is the official language of the Tang Dynasty Cantonese today?

Hou Sizhi is from Jujube Pear, and his pronunciation is incorrect, so as to inform him to make corrections and allow suggestions. Tu Po said in the same column: "Today, Tu Po, (chicken cloud) Gui, (pig cloud) Zhu, (fish cloud) Yu, (donkey cloud) wisp, (clouds) can not live (eat clouds), and empty (eat) knots (mi cloud). Smile at Cui Yuxian. If you stop thinking and smell it, you will get angry. You can say, "I know thinking can't read." I used it. What are you laughing at? "Sacrifice can be a matter of chickens and pigs, and then laugh and let go. As I said at the beginning of this paragraph, I came from a humble background and Hou Sizhi had a bad accent, so I made a joke. Generally speaking, this passage is understood as the phonology used by the bottom and the court is different. Because this netizen is from Guanzhong, he ignored the opening sentence and misinterpreted it as an incorrect Guanzhong accent, which was laughed at. No matter how smart you are, you have your own so-called logical flow. However, what happened to Luoyang's disorderly entry? Where did you see it? By misinterpreting the material to answer questions, the malice is obvious ... In addition, there are comments by An Yisheng in the comments. Through the distinction between fish and danger, it is considered that what Hou said is not Guanzhong phonology, but closer to Luoyang, Hebei Province.
