Since the pre-Qin period, the land of Bashu has accommodated many immigrants from east, west, north and south. During the Qin and Han dynasties, the migration of the surrounding areas to Shu objectively brought about the surrounding multiculturalism. During the Sui, Tang and Five Dynasties, the economy of Bashu was prosperous, and literary works were flourishing, which attracted a large number of scholars to enter and live in Sichuan, which not only made Sichuan one of the most prosperous regions in China, but also promoted the great exchanges between Shu culture and various cultures.

Due to the continuous convergence and blending of Bashu multi-cultures, Bashu's unique customs, culture and folk characteristics have been formed. According to the ancient history of Bashu, Four Treasures of the Study in Bashu: Shu brocade, Shu Xuan, Shu embroidery and Shu Xiang are unique cultures of Bashu.

Fragrance, not only to raise the nose, but also to raise the spirit and preserve health, enlighten the mind and wisdom, which is a core principle of traditional fragrance-making technology. It is precisely by adhering to this concept that traditional fragrant products have not only become fragrant things, but also become drugs for resuscitation and health preservation, which have won wide welcome from all walks of life in the long historical period from Qin and Han Dynasties to Ming and Qing Dynasties.

It can be seen from the "four-point incense burner" in the early years of the Western Han Dynasty that the lotus fragrance was ready at that time. After the Han dynasty, the compatibility level of spices has been continuously improved, and the types of incense formulas have become increasingly rich. Until the Ming and Qing Dynasties, the combination of incense was the mainstream.
