Why is "Third Era of Northern Domination" trending?

Wikipedia Overview

The Third Era of Northern Domination refers to the third period of Chinese rule in Vietnamese history. The era starts from the end of the Early Lý dynasty in 602 to the rise of the local Khúc family and other Viet warlords in the early 10th century. The Khúc were part of a local sinicized elite that continued to rule in the name of northern Chinese dynasties as jiedushi despite being de facto independent. The Southern Han removed them from power in 930 but lost control over the region due to an uprising that culminated in their defeat at the Battle of Bạch Đằng in 938 by the Viet leader Ngô Quyền. This period saw three Chinese imperial dynasties rule over what is today northern Vietnam: Sui, Tang and Wu Zhou. The Sui dynasty ruled northern Vietnam from 602 to 618, and briefly reoccupied central Vietnam in 605. The successive Tang dynasty ruled northern Vietnam from 621 to 690, and again from 705 to 880. Between 690 and 705, the Tang dynasty was briefly interrupted by the Wu Zhou dynasty which maintained Chinese rule over Vietnam.
