上皇御宫之南楼，肃宗拜庆楼下，呜咽流涕不自胜，为上皇徒步控辔，上皇抚背止之，即骑马前导。
The Retired Emperor arrived at the South Tower of the Imperial Palace. Emperor Suzong kowtowed and celebrated under the building, weeping uncontrollably and personally controlling the carriage's reins for the Retired Emperor, who patted his back to stop him. Emperor Suzong rode his horse in front to lead the way.
