Why did the rulers of the tang and song dynasties support the arts and literature ?

The rulers of the tang and song dynasties support the arts and literature because it attracts the attention of foreigners to the country in order to promote commercialization.

Here is a summary of all that art and literature have caused in that region:

Chinese painting during the Song Dynasty and the Tang Dynasty reached a new level of sophistication with the development of landscape painting. The emphasis on landscape painting in the Song period was grounded in Chinese philosophy; Taoism emphasized that humans were only small stains between the vast and vast cosmos, while neo-Confucian writers often sought the discovery of patterns and principles that believed to cause all social and natural phenomena. The manufacture of glazed and translucent porcelain and celadon with the complex use of enamels was also developed during the Song period. Longquan celadon wares were particularly popular in the Song period.

The elite of the nobility devoted themselves to the arts as accepted pastimes of the learned academic-official; these pastimes included painting, composing poetry and writing calligraphy. Poetry and literature profited from the growing popularity and development of the form of poetry ci. Huge encyclopedic volumes have been compiled as works of historiography and dozens of treatises on technical subjects. The genre of Chinese travel literature also became popular with the writings of the geographers Fan Chengda (1126-1193) and Su Shi, the latter of whom wrote the "excursion essay" known as Record of Stone Bell Mountain, which used persuasive writing to argue for a philosophical point.

Theater and drama in China go back to the music academy known as Pear Garden, founded in the early 8th century during the Tang Dynasty. However, historian Stephen H. West states that the capital of the Northern Song era Kaifeng was the first royal center where the performing arts became "an industry, a conglomerate involving theater, gambling, prostitution and food." of consumption by marketers and scholars -officials, he states, "accelerated growth in performance and food industries," asserting a direct link between the two because of their proximity in cities. Of the fifty-fifty theaters located in Kaifeng's "pleasure districts," four were large enough to entertain audiences of thousands of people each, attracting huge crowds that the neighboring companies took advantage of.
