The Lê royalists under Lê Ninh, a descendant of the Royal family, escaped to [[Muang Phuan]] (today [[Laos]]). Marquis of An Thanh [[Nguyễn Kim]] summoned the people who were still loyal to the Lê emperor and formed a new army to begin a revolt against Mạc Đăng Dung. Subsequently, Nguyễn Kim returned to Đại Việt and led the Lê royalists in a sixty-year-long [[Lê–Mạc War|civil war]]. In 1536 and 1537, [[Lê Trang Tông|Nguyên Hòa]] sent two envoys to Beijing to ask [[Jiajing Emperor]] of Ming Dynasty to send army fight against the Mạc to [[Revival Lê dynasty|restore the Lê Dynasty]]. Many Ming officials like [[:zh:毛伯溫|Mao Bá Ôn]] showed strong supports for the Lê royalists and urged Jiajing Emperor for prepare a military campaign. The Ming Emperor agreed.
