 There were also very large encyclopedic works written in the Song period, such as the Four Great Books of Song compiled first by Li Fang in the 10th century and fully edited by the time of Cefu Yuangui in the 11th century. The largest of these was the 1013 publication of the Prime Tortoise of the Record Bureau, a massive encyclopedia consisting of 9.4 million written Chinese characters divided into 1000 volumes. There were are also rhyme dictionaries written during the Song dynasty, such as the Jiyun of 1037. Although Neo-Confucianism became dominant over Buddhism in China during this period, there was still a significant amount of Buddhist literature. For example, there was the collection of Zen Buddhist kōans in the Blue Cliff Record of 1125, which was expanded by Yuanwu Keqin (1063 – 1135). 'Travel record literature' ('youji wenxue') was also a popular category of literature during the Song period, which was accounts of one's own travel experiences typically written in narrative or prose styles, and included authors such as Fan Chengda (1126 – 1193). A great example of Chinese travel literature in the Song period would be Su Shi's (1037 – 1101) Record of Stone Bell Mountain.
