Although Li Longji and Yang Yuhuan didn't leave any children, according to records, Yang Yuhuan was pregnant, but later she had an unexpected abortion. On the other hand, it can be considered that due to Li Longji's advanced age, the possibility of having children is very small.

Because Yang Yuhuan is actually Li Longji's daughter-in-law, Li Longji lusted after beauty and took it away from her son, so it was full of twists and turns, which is why Yuhuan was never regarded as a queen but only a imperial concubine.
