Saint Lucy was born to Catholic parents in Sichuan in 1815. Devout and pious from a young age, she made a vow of chastity at the age of 12.

At the request of local priests, she taught the faith for many years in schools and in a convent as well as doing missionary work.

In 1862, she went with Father Wen Nair to Jiahanlong to found a mission. Many of the Friars, including Father Wen, were arrested and executed. The day after the execution, Lucy was put on trial. She refused to recant her faith, and was beheaded. Her feast day is February 19.
