According to the timeline of her previous life, her father broke his leg while working at his part-time job. From then on, her brother had to take on the heavy burden of being the breadwinner of the family and started to do odd jobs everywhere. It took a great toll on his physical well-being, where he bore a lot of pressure on his shoulders, quite literally. He often did not eat well and cared only about making more money.
It was also because of this that her brother's stomach had a ticking time bomb. When she found out, her brother was already in the final stage of stomach cancer.
Thinking of this, Xia Wan was even more determined to make her business succeed. She wanted to train her brother well so he wouldn't have to do hard labor.
