There should be no concubines. Whether it is Zhao Hede, Zhang Lihua, Wu Hui, Yang Guifei, Wan Guifei, etc., or even the famous Chen Concubine Hai Lanzhu and Dong E Concubine, they are not special favors. When Zhao Hede entered the palace, her sister Zhao Feiyan was also very favored. In addition to Zhang Lihua, Chen Shubao also favored Kong Guifei and Gong Guifei. When Concubine Wu Hui was still there, there were other concubines who had children. Concubine Yang was once sent home because she was jealous of Xuanzong's favoring others, but Concubine Wan Guifei did not. Having said that, when Concubine Chen and Concubine Dong E were still alive, there were concubines in the palace giving birth.
There are two queens, Queen Yuwen Yuanying of the deposed Emperor Yuanqin of the Western Wei Dynasty and Queen Zhang of Ming Xiaozong. Dugu Jialuo is not a special favorite. When she was alive in the last years of Emperor Kaihuang, Yang Jian favored Yuchi Jiong. After the death of Dugu Jialuo, Yang Jian doted on Mrs. Chen, Mrs. Xuanhua, and Mrs. Cai, Mrs. Ronghua.
