Qui es va casar amb Togoon?

An Tư (chữ Hán: 安姿, 1267 – ?), was a princess during the Trần dynasty (1225–1400), the youngest offspring of emperor Trần Thái Tông. The exact year of her birth and death are unknown. The Đại Việt sử kí toàn thư (1675) only records that “the servants were ordered to give Princess An Tư to Togon to buy time”.
