Because they owned two stores, Qin Xue and her friends didn't need to worry about money. Qin Xue never asked The Qins for living expenses, because she made money from an online store she started with her college friends. During the holidays, she also worked at Mr. Chu's company and later as a doctor. This money was entirely given to An Xiaochen.
Back then, neither An Xiaochen nor Nangong Beiying knew that Qin Xue had invested all her assets. In other words, if the gym and tea shop did not make money, Qin Xue would be penniless.
Fortunately, they were lucky enough to not only avoid losing money but also earn quite a bit. This is how they managed to live comfortably and why An Xiaochen had money to give back to the orphanage.
