When Túc Tông came to the throne, he declared that in the next year (1505), the era name will be changed from his father's old one, Cảnh Thống (景統) to Thái Trinh (泰貞). However, Túc Tông died before 1504 was over; so, throughout his short reign, he still used the era name Cảnh Thống and the name Thái Trinh was never put into use. His successor, Lê Tuấn changed the era name to Đoan Khánh.
