who was the last ruler of the tang dynasty
Tang dynasty Zhu Wen, originally a salt smuggler who had served under the rebel Huang, surrendered to Tang forces. By helping to defeat Huang, he was granted a series of rapid military promotions.[71] In 907 the Tang dynasty was ended when Zhu Wen, now a military governor, deposed the last emperor of Tang, Emperor Ai of Tang, and took the throne for himself (known posthumously as Emperor Taizu of Later Liang). He established the Later Liang, which inaugurated the Five Dynasties and Ten Kingdoms period. A year later Zhu Wen had the deposed Emperor Ai poisoned to death.
Tao Te Ching The first reliable reference to Laozi is his "biography" in Shiji (63, tr. Chan 1963:35–37), by Chinese historian Sima Qian (ca. 145–86 BCE), which combines three stories. First, Lao Tzu was a contemporary of Confucius (551–479 BCE). His surname was Li (李 "plum"), and his personal name was Er (耳 "ear") or Dan (聃 "long ear"). He was an official in the imperial archives, and wrote a book in two parts before departing to the West. Second, Laozi was Lao Laizi (老來子 "Old Come Master"), also a contemporary of Confucius, who wrote a book in 15 parts. Third, Laozi was the Grand Historian and astrologer Lao Dan (老聃 "Old Long-ears"), who lived during the reign (384–362 BCE) of Duke Xian (獻公) of Qin).
