What is the pronunciation of "Daozang" (dào zàng or dào cáng) and how to understand it?

When some scholars of Tibetan Buddhism read Tibetan, they thought that it was created by imitating the Buddhist Tripitaka. In fact, during the Southern and Northern Dynasties, Lu compiled a catalogue of Taoist Sanzang in 47 1 year, much earlier than the earliest Buddhist Tripitaka. The earliest existing Taoist collection is the Ming version. Baiyun Temple, originally hidden in the Tibetan capital of North Road, is now in the National Library of China. The formal integration of Taoism and calligraphy began in Tang Kaiyuan (713-741). Since then, the dynasties of Song, Jin, Yuan and Ming have successively compiled Taoist scriptures. There was a Taoist collection in the Qing Dynasty. Contemporary books include Taoist scriptures outside Tibet, Taoist scriptures in Dunhuang and Taoist scriptures in China. Kaiyuan Taoist Collection is the first official and complete Taoist Collection in the history of China.
