Lee Ya-Ching was born in Canton, China in 1912. As an only child who lost her mother at a young age, Ya-Ching was raised by her father and grandmother. Under her father's guidance she learned many skills, including martial arts, some previously restricted to male children. Ya-Ching attended English schools in Hong Kong and Shanghai and at the age of 16 was sent to London to attend finishing school.
In 1929 at the age of 17, Ya-Ching went to Geneva, Switzerland. It is there that she took her first ride in an airplane and vowed to learn how to fly. She enrolled in Ecole Aero Club de Suisse and, in 1934, became the first woman to receive a pilot's license from the school. Determined to continue her education, Ya-Ching went to the United States and attended the Boeing School of Aeronautics in Oakland, California in 1935. In November of that year she became the first woman licensed through the Boeing School. Upon completion of her training at the Boeing school Ya-Ching returned to China and began campaigning for a Chinese pilot's license, eventually obtaining the license in 1936. Seeing a need to train new pilots, Ya-Ching and some fellow pilots opened a civilian flying school in Shanghai in 1936.
When Japan invaded China in 1937, Ya-Ching volunteered to fly for her country, but was refused. Undeterred, she served her country by establishing hospitals. Leaving Shanghai for Hong Kong just before the city fell, she was finally given the opportunity to fly for China by piloting Red Cross planes ferrying supplies from Hong Kong to Canton. Realizing that China needed aid and supplies, Ya-Ching embarked on a Goodwill Tour of the United States and Canada in 1938. When the war prevented her return to China, Ya-Ching continued the tour expanding her appearances into South America.
Not much is known of Ya-Ching's life after the war. She returned to Hong Kong for a number of years. In the 1960's she returned to California, where she died in 1998 at the age of 86.
