Recommendation through Observation in the Han Dynasty (206 BC - 220)
In 136 BC during the reign of Emperor Wudi (156 BC - 87 BC), the government introduced a system which was named 'taixue'. Usually the students were provided with a free diet and mainly studied the classical Confucian books. Following examinations, those with good marks would directly be given official titles.
In the Han Dynasty there had been no system for testing a person's ability, and the most prevalent method was merely through observation. Officials would see who was intelligent and recommend individuals to their superior. This obviously restricted the source of talented people and did little to provide any kind of equality for the population as a whole. Such a system could only lead to nepotism and corruption and the need for a different means of selection had to be sought.
