6 Schools of Sima Tan
Sima Tan (司馬談) 165-110 BC was a grand historiographer and astrologer of the Western Han dynasty, who classified the philosophy of his time into six main traditions. Of the six, Sima Tan favoured Daoism as the one school among them with the breadth of thought to encompass the others.
4 Books of Zhu Xi
Zhu Xi (1130-1200) was a Confucian scholar of the Southern Song (1127-1276). Incredibly learned and prolific, he ushered in a Neo-Confucian revival. His commentaries on the Four Books, which he singled out as the core classics of the Confucian canon, became prescribed reading for government officials.
