What are the classical writings of the Confucianism, Buddhism and Taoism in the Chinese tradition, and where can I buy the genuine ones? The more, the better.

During the period of Emperor Wu of the Han Dynasty, he "dismissed the hundred schools and honored only the Confucians". The emergence of the "Five Classics", that is, "Poetry", "Book", "Rites", "Yi", "Spring and Autumn". After the Han Dynasty, the Analects of Confucius and the Book of Filial Piety were added to the list, which were called the "Seven Classics". In the Tang Dynasty, there were three Rites (Zhou Li, Rites of Passage, Li Ji) and three Chuan (Zuo Chuan, Gongyang Chuan, Gu Liang Chuan), which, together with Poetry, Shu and Yi, were known as "Nine Chuan". When Emperor Wenzong of the Tang Dynasty added the Analects of Confucius and the Book of Filial Piety, which had already been included in the Trail of Paths in the Han Dynasty, and supplemented it with the Book of Erya to form the Twelve Scriptures. In Songren, the addition of Mencius formed the "Thirteen Classics", which had a special status in feudal society. The "Thirteen Confucian Classics" refers to the 13 Confucian books that the feudal rulers successively "legalized" as "classics", forming the "Thirteen Classics" with a special status in feudal society. Today, the "Thirteen Classics" are still of great value as ancient books reflecting the historical situation of the pre-Qin Dynasty. They are "The Book of Poetry", "The Book of Shang", "The Rites of Zhou", "The Rites of Passage", "The Book of Rites", "The Book of Zhou", "The Book of Zuo", "The Book of Gongyang", "The Book of Guliang", "The Analects of Confucius", "The Book of Erya", "The Book of Filial Piety", and "The Book of Mencius".
