Meng Tian

Meng Tian (died 210 BC) was a Chinese inventor and military general of the Qin dynasty who distinguished himself in campaigns against the Xiongnu and in the construction of the Great Wall of China. He was the elder brother of Meng Yi. He descended from a great line of military generals and architects. His grandfather, , was a general from the era of King Zhao; and his father, , was also a general who served as a deputy to Wang Jian.
Life.
By the time the Qin state conquered the other six states and began its reign over a unified China in 221 BC, the nomadic Xiongnu had grown into a powerful invading force in the north and started expanding both east and west. Qin Shi Huang, the first emperor of the Qin dynasty, sent a 300,000-strong army headed by Meng Tian to drive the Xiongnu northward for 1,000 "li" (about 416 km) and began work on what has become known as the Great Wall to guard against invasion. The defensive works he began were said to extend over 10,000 "li" (4,158 km) "from Lintao to Liaodong and even extended across the Yellow River and through Yangshan and Beijia.", that is, from the southwest corner of the Ordos Loop to the Yellow Sea. Yangshan and Beijia are hard to locate, but the wall ran along the Yellow River and included all of the Ordos Loop.
Meng Tian's ingenuity can be seen in the efficient (though inhumane) building policy, the consideration of topography, and the utilisation of natural barriers. Meng Tian supervised the construction of a road system linking the former Yan, Qi, Wu and Chu areas, as well as a number of roads especially for imperial use. The system eventually formed played an extremely important role in ancient transportation and economic exchanges. He is also traditionally, if erroneously, credited with having invented the "Ink brush" (毛筆) and is specially remembered at the "Huzhou Pen Festival", which developed from festivities at his ancestor temple. Meng Tian is also credited with inventing the "zheng" (筝), a bridge zither with twelve or thirteen strings.
When Fusu, Qin Shi Huang's eldest son and the crown prince, was exiled to work at the northern border for disputing his father's policies, Meng Tian was ordered to assist the prince — a task he had accomplished loyally. When Qin Shi Huang died, Meng Tian's death was caused by Zhao Gao who forged a letter from Qin Shi Huang. He was forced to commit suicide in prison, and his family was killed. Three years after his death, the Qin dynasty collapsed.
In Popular Culture and Legacy.
Meng Tian sometimes appears as a door god in Chinese and Taoist temples, usually paired with Fusu.
He is one of the 32 historical figures who appear as special characters in the video game "Romance of the Three Kingdoms XI" by Koei. He also appears as a non-playable character in "Prince of Qin".
In the manga series Kingdom, Meng Tian is known as "Mou Ten", a Qin General and the eldest son of Great General Mou Bu (Meng Wu). He looks different than his father and his younger brother Mou Ki. He has a feminine appearance, with shoulder length black orange hair and a pink robe over his armor. He usually leads his forces alongside Wang Ben/Ou Hon and Li Xin/Ri Shin, but his tactical expertise is higher and better known due to him being a graduate of the Strategist Academy and the top student under Lord Changping's school. He acts as a referee or peacekeeper for Wang Ben/Ou Hon and Li Xin/Shin, who are shown to despise each other and argue constantly in the series.
