Du Mengxin was not from Beijing, but her family background was extraordinary.
A few days ago, Du Mengxin's father came to Beijing for a meeting and took the opportunity to catch up with some old friends. He brought his daughter along, who, to their pleasant surprise, ended up meeting Song Wenbin. It turned out that her father's old friends were from the Song Family.
Given that their parents were old acquaintances and Beijing could be tough for a young girl working alone, Song Wenbin's father urged his son to take care of her. Song Wenbin found Du Mengxin rather appealing in all aspects, and he was considering getting to know her better. So he invited her to the "Joyous Christmas Eve" party.
Du Mengxin knew that such balls would typically involve prominent figures from the Capital City, and it would not hurt to meet a few more people. So, she readily agreed.
