In the previous seismological literature, the Changjiang earthquake of 1920 in Hainan Island was carried. Its basic parameters were set as follows: Seismogenic time: 1920,5,27,13-49-30. Epicenter: N19 ° 0E109 ° .0 Magnitude: 5 1/4 The accuracy of the epicenter is 5 types, the error is more than 100 km. Reference location, said the Changjiang area, and some literature is called “Canton dam earthquake.” In recent years, when compiling the historical data of Guangdong Province, I noticed that the “Changjiang Earthquake” was a historical phenomenon in the history books of Chronicles such as “Guangdong Tongzhi Draft” in 1924, “Ganchang County” in 1929, “Zhi County” in 1935 and 1943 "Qiong shore
