"Whoever steals money first, accidentally leaves her, and a month ago, goes to Fuliang to buy tea" (Bai Juyi's Pipa Trip) reflects the businessman's life of chasing profits; "The guest line in the wilderness, than the house closed. Ask the people in the house to be the best merchants "(Yao She's" Zhuang Juye ") describes the situation of folk business fever at that time. "The night market is full of lights shining in the blue clouds, and there are many high-rise tea drinkers. Now, unlike usual, the wanderer is singing and listening.

It was the eunuchs in the palace and eunuchs who did it. The eunuch, with documents in his hand and the emperor's orders in his mouth, shouted at the petrified palace. ..... half a horse, one foot silk, charcoal to the cow's head. " The "yellow messenger" and "paper in mouth" in the poem (Bai Juyi's "Selling Charcoal Weng") vividly describe the momentum and arrogance of the royal procurement officials, and also illustrate the historical truth of the government procurement in the East and West cities and the commercial prosperity in Chang 'an, and vividly describe the market transactions in the Tang Dynasty. As a political, economic and cultural center, Chang 'an, Tang Dou, attracted the attention of the world at that time for its architectural style, market layout and local customs. The urban architecture in Tang Dynasty has the leading level in the world. "A hundred schools of thought are like a chess game, and Twelfth Street is like a vegetable garden." (Bai Juyi's "Climbing Guanyin Terrace and Looking at the City") "Four hundred and eighty halls in the Southern Dynasties, how many towers are misty and rainy." Isn't it a true portrayal of the prevalence of Buddhism in the Southern Dynasties?
