How did Arju and A meet?

Arjun and Azi are sisters. They are all Duan's daughters. Zhu is my sister, and Ah Zi is my sister. Before meeting her, Ah Zhu didn't know that she was Duan's daughter. At that time, she worked as a maid in Gusu. Later, Ah Jun found that he and Ah Zi had the same symbol, which was an opportunity for them to get to know each other. Finally, with the help of her mother Ruan, Azi recognized Aju, and the two sisters got to know each other.
