What happened to Swallow and Yongqi? Does he and Xin Rong have children?

Yongqi Xinrong consummates the marriage. I don't know if I have children, but consummation is absolute, because Yongqi mistook Xinrong for a swallow one night and got married. Yongqi and Swallow finally met in the sea of flowers. Swallow played the violin of Turtledove, and Yongqi approached step by step. Finally, Yan Yong was happy!
