Live up to Empress Xiao and Live up to Song Dynasty

Wei Gang traveled back in time to the Yongxi reign of Emperor Taizong of the Northern Song Dynasty, and came to Youzhou to help his fiancée Li Suying find her father Li Yuanwai who had disappeared after being stolen by thieves. It happened that Emperor Jingzong of the Liao Kingdom was critically ill, and Queen Xiao Chuo went on a tour to Youzhou incognito. Wei Gang gradually fell in love with Empress Xiao during the brutal power struggle, helped Empress Xiao consolidate the power of the Liao Kingdom, and resisted Song Taizong's Yongxi Northern Expedition. Between love and power, Empress Dowager Xiao chose the former because of her ambition for the world, and Wei Gang was forced to return south. Facing the invasion of Liao soldiers, Wei Gang sided with Prime Minister Kou Zhun, and Emperor Zhenzong of the Song Dynasty personally marched and defeated the Liao army at the foot of Chanzhou City. Song and Liao signed the Chanyuan Alliance, and there has been no war on the border between the two countries for a hundred years. Li Suying entered the palace as a concubine, and Wei Gang never returned to the Liao Dynasty or abandoned the Song Dynasty. He dealt with the queen mothers of the two countries and completed the pattern of the unification of China in a comic way. Song and Liao were originally one family!
