Until the age of 22, at the recommendation of Feng Jingru, Cai Gongshi met Sun Yat-sen for the first time and joined the Chinese League.
Since then, he has often accompanied Sun Yat-sen and become a staunch revolutionary.
In 1908, he launched an uprising with Huang Xing in Qinzhou, Guangxi. In 1911, he participated in the Xinhai Revolution and instigated the independence of Jiangxi. In July 1913, after the defeat of the Second Revolution, Cai Gongshi and Sun Yat-sen went into exile in Japan. In March 1916, the two returned to Shanghai together, and participated in the Patriotic Movement and the War of Defending France, and never left Sun Yat-sen.
Because he had traveled east to Japan twice, he spoke Japanese very well, and during his time as a secretary to Sun Yat-sen, as long as it involved Japanese affairs, he mediated from it at the same time.

On May 1, Cai Gongshi and his party of 18 people took a special train into Jinan, and on the morning of May 3, there was a sudden burst of gunfire outside the Negotiation Office, at this time, Cai Gongshi found that a group of Japanese soldiers hid in the Opposite Christ Hospital to shoot at the Northern Expeditionary Army, and soon after, they began to wantonly hunt down and kill all the soldiers and civilians in the city, creating the "Jinan Massacre" that shocked China and foreign countries.
At 9 p.m., more than 50 Japanese soldiers with guns broke into the office, tore up the flag of the Nationalist government, as well as the portrait of Dr. Sun Yat-sen, and forcibly plundered documents. Witnessing everything, Cai Gongshi couldn't bear it anymore and sternly condemned the sabotage of the Japanese army in Japanese.
At this time, a Japanese soldier suddenly rushed up, knocked him down with one punch, made him kneel down to apologize, and after being rejected, several Japanese soldiers followed. When he pushed Cai Gongshi to the ground, he cut off his ears, and then cut off his nose. Enduring the pain, Cai Gongshi was righteous and scolded incessantly.
The enraged Japanese soldier directly inserted the knife into his mouth, stirred it twice, cut off his tongue, and then gouge out her eyes, Cai Gongshi's whole body was blurred with blood and flesh, and he was killed on the spot. The japanese soldiers, who were not relieved, killed Cai Gongshi's entourage one by one.
In order to cover up the crime, the Japanese soldiers burned the bodies of the victims in a fire and buried them hastily in the courtyard of the office.
The only survivor, Zhang Hanru, a service soldier, heard the sound of gunfire, pretended to fall to the ground in response, and then took advantage of the darkness and cut a short rope to escape, which made the tragedy public.
After the Northern Expeditionary Army withdrew from Jinan, the Japanese army entered the city again, and then carried out massacres and looting, with thousands of people, and hundreds of wounded members of the Northern Expeditionary Army who could not be evacuated were also slaughtered by the Japanese army. According to later data, in the Jinan massacre, 6123 Chinese soldiers and civilians died, injured 1700 people, and suffered 30 million yuan in property losses.
