Jia Sitang, a researcher in Oracle Bone Inscriptions, who are you referring to? What achievements have you made?

It is an ancient script of Shang and Zhou Dynasties in Oracle Bone Inscriptions, and divination is often engraved on tortoise shells or animal bones. It is called "the earliest Chinese character". Since the discovery of Oracle Bone Inscriptions in the 24th year of Guangxu, there has been an upsurge of Oracle Bone Inscriptions research in the late Qing Dynasty. At first, scholar Sun Yirang explained Oracle Bone Inscriptions. Later, a large number of scholars also joined the ranks of Oracle Bone Inscriptions studies, among which "Oracle Bone Inscriptions Four" is the most famous. They made great contributions to the study of Oracle Bone Inscriptions and laid the foundation for the later study of Oracle Bone Inscriptions. The reason why they are called "four halls of Oracle bones" has two meanings: these four people are the most outstanding Oracle bone researchers, and they all have the word "Tang" after their names. Chen Zizhan, a famous professor at Fudan University, once said, "Oracle bones have four halls, Guo Dong and Wang Luo". The four men are Guo Moruo, Dong Zuobin, Luo Zhenyu and Wang Guowei. Of the four schools in Oracle Bone Inscriptions, Luo Zhenyu and Wang Guowei started their research earlier, while Guo Moruo and Dong Zuobin started their research later. The specific ranking of the four has been inconclusive. Just list their contributions to the study of Oracle Bone Inscriptions as follows:

Luo Zhenyu plays a very important role in the study of Oracle Bone Inscriptions. He is called the founder of Oracle Bone Inscriptions, and Luo Zhenyu was good at textual research since he was a child. His contribution is mainly to discover the location of Oracle Bone Inscriptions. Since the discovery of Oracle Bone Inscriptions, there has been a long-standing debate about where Oracle Bone Inscriptions came from. After extensive material collection and serious textual research, Luo Zhenyu proposed that "the name of Emperor Yin was engraved more than ten times, but he suddenly realized that his divination was a legacy of Yin." He correctly judged that the land of Oracle bone inscriptions was not the legendary land of Shandong and Tangyin, but the ruins of Yin Ruins in Xiaotun Village, Anyang, Henan Province. He was also the first person to write calligraphy with Oracle Bone Inscriptions. Together with Wang Guowei, he sorted out and studied Oracle Bone Inscriptions, which confirmed the phenomenon of merging books in Oracle Bone Inscriptions. Their research is called "Luo Wang Study".

Wang Guowei's contribution to Oracle Bone Inscriptions is first manifested in his textual research and explanation of Oracle Bone Inscriptions. 19 15, Wang Guowei published the Textual Research on the Place Names Seen in Oracle Bone Inscriptions of Yin Ruins, and made textual research on eight place names, such as Meng, Yong, Hao, Fei, Si and Pin, and proved that "Yin Sacrifice" refers to joint sacrifice and "External Sacrifice" refers to social sacrifice. 19 17 published the book Taxi and Wang Kao in Oracle Inscriptions in Yin Ruins, which not only verified the existence of some characters in Shang and Zhou Dynasties, but also confirmed Sima Qian's records about Yin Benji in Historical Records, corrected some mistakes in Historical Records and proved that it was indeed a history of faith. Another contribution of Guo Wang is to summarize the "double evidence law" of unearthed documents and books, which is not only of great help to the study of Oracle bones, but also enlightens general academic research.

Guo Moruo's research on Oracle Bone Inscriptions started late. He began to study the history of Oracle Bone Inscriptions and Shang Dynasty in 1928, and later studies were able to catch up. Guo Moruo has published many works by Oracle Bone Inscriptions, including Ancient Society in Oracle Bone Inscriptions, A Study of Oracle Bone Inscriptions, A Collection of Oracle Bone Inscriptions, Continuation of Ancient Chinese Characters, etc. His contribution to Oracle Bone Inscriptions is mainly manifested in the textual research on the politics, economic system and social production and life of the Shang Dynasty, as well as his unique views on slavery, private property, clan nobility and other issues. On this basis, he studied the system of succession to the throne and the form of marriage and family in Shang Dynasty, and concluded that Shang Dynasty was a bronze age and a slave society. Guo Moruo not only researched more than 500 places in Oracle Bone Inscriptions, but also developed a set of methods to study place names: place name association method, which provided convenience for archaeological work.

Dong Zuobin's greatest contribution to the study of Oracle bones is to establish the bone dating method. His book A Case Study of Oracle Bone Inscriptions Dating is recognized as an epoch-making masterpiece in the history of China and Oracle Bone Inscriptions. Different from the first three, Dong Zuobin participated in the excavation of Yin Ruins many times and presided over the arrangement of Oracle Bone Inscriptions. On this basis, he proposed using Oracle Bone Inscriptions to date generations by stages. Oracle Bone Inscriptions can be divided into five periods: the first period is Pan Geng, Xiao Xin, Xiaoyi and Wu Ding; The second phase is Zu Geng and Zujia; The third period is Lin Xin and Kangding; The fourth period is Wuyi and Wen Ding; The fifth phase is the first phase of cooperation with Di Xin, which greatly promoted the study of Oracle Bone Inscriptions. In addition, on the basis of studying Oracle bones, Dong Zuobin formed his own unique views on the calendar and etiquette of Yin and Shang Dynasties.
