In 582, Emperor Wen, to further honor Emperor Ming, offered to take one of his daughters as the wife to Emperor Wen's favored son Yang Guang the Prince of Jin. Emperor Ming, after trying to divine the fortunes, determined that all of his daughters were inappropriate choices—but then remembered that he had a daughter, who was born in the second month of the year and thus, by superstitions of the time, considered ill fortune and therefore was raised by her maternal uncle Zhang Ke (張軻). He summoned her back to the palace, and the diviners indicated that she would be a fit, and therefore she was married to Yang Guang. (Emperor Wen also wanted to give his own daughter Princess Lanling to Emperor Ming's son Xiao Yang (蕭瑒) the Prince of Yi'an, but for reasons unclear ultimately did not do so.) Because of this marital relationship, Emperor Wen decided to withdraw the Commandant of Jiangling from Jiangling. Thereafter, for a brief duration, Emperor Ming was able to rule his state with decreased interference from Sui. In 583, when Sui moved its capital from the old city of Chang'an to a nearby, newly constructed capital Daxing (大興), Emperor Ming sent his crown prince Xiao Cong to congratulate Emperor Wen. In spring 584, Emperor Ming himself went to the new capital to pay homage to Emperor Wen, and both of them dressed in imperial garbs, although Emperor Ming dressed slightly less impressively to show his status as a vassal.
