The Wanjuanlou (萬卷樓; 万卷楼; Wànjuànlóu; 'tower of 10', '000 volumes of writings') – a tourist attraction in the Xishan Scenic Spot, Shunqing District, Nanchong, Sichuan – is named the source of the culture of the Three Kingdoms period by the Sichuan provincial government. The tower was constructed in the early third century (222–237) during the Three Kingdoms era. It was also the place where Chen Shou studied in his early life. It was destroyed in the 1960s after years of neglect, but was rebuilt in 1990 by the Chinese government at a cost of four million yuan.
