Aside from the Prince Yu Couple and Yang Cheng'an, who remained to take care of Long Ruoshui, Old Master Yang and others arrived in the Capital early. Considering Long Ruoshui was about to give birth, they returned to Yangliu village the day after the full-month celebration, only to encounter on their way the messenger Yang Cheng'an had sent to announce the joyous news: Long Ruoshui had given birth to twin sons on the morning of the sixth day of the seventh month.
Upon hearing the news, Yang Mengchen discussed with Long Xuanmo and immediately sent a generous gift to celebrate.
With the consent of Old Master Yang and the others, Yang Cheng'an decided that his second son should take his maternal grandfather's surname Long, both to honor his grandparents and to continue their family line.
