Sun Wan

Sun Wan, born in the early 20th century, with her specific birth year not detailed. She was one of Sun Yat-sen's children with his first wife, Lu Muzhen, and had a younger brother, Sun Ke, as well as two sisters, Sun Yan and Sun Wan. Sun Wan's life was relatively difficult; during her childhood, her family faced financial hardships. Her living conditions improved only after she was brought to live with Sun Yat-sen.

Sun Wan studied abroad in the United States, attending California State University in the Department of Literature. During her studies abroad, she was cared for by someone arranged by Sun Yat-sen, entrusted to Wang Boqiu, who was then studying at Harvard University. Wang Boqiu came from an official aristocratic family, joined the Tongmenghui during his studies in Japan, and became acquainted with Sun Yat-sen. He was an outstanding student and capable, earning Sun Yat-sen's trust and favor. Sun Wan and Wang Boqiu gradually developed feelings for each other, and they married in 1914.

In 1916, Sun Wan gave birth to a daughter named Wang Hui. In 1919, while returning to China by cruise, she bore a son named Wang Hongzhi for Wang Boqiu. Wang Boqiu was already married in China and kept his wife a secret until their return to China, when Sun Yat-sen learned of this affair. Sun Yat-sen was angry about Wang Boqiu's private life but hoped he would divorce his wife, though this did not happen. Due to family pressure and social opinion, Wang Boqiu was unable to divorce his wife, which led to the end of Sun Wan's first marriage, and her children from that marriage were raised by Wang Boqiu.

In March 1921, Sun Wan married Dai Ensai in Macau, who was then serving as the mayor of Wuzhou, beginning her second marriage. Dai Ensai had studied at St. John's University in Shanghai and Tsinghua University in Beijing, earning a Ph.D. in International Law from Columbia University in the United States. Upon returning to China, he also held some influence in politics. They had a daughter, Dai Chenggong, and a son, Dai Yongfeng. Sun Wan subsequently moved to Macau with her husband. After Dai Ensai's death, she lived with her daughter.

Sun Wan passed away in Macau on June 3, 1979, at the age of 84. Her life was marked by multiple marriages and relocations, with complex family relationships, and she lived between different countries.
