My Sister Became Capital After Not Being a Stepping Stone

My elder sister gave up her studies for the sake of the family and supported her younger sister through her Ph. D. But her sister mocked her: "People with low education like you will never understand our world." My sister silently turned on the computer and showed the business plan she had just completed. Three days later, an upstart in technology came to our door with a multi-million contract: "Mr. Su, only you can lead this project." Her family members who once looked down upon her are now lining up outside the door waiting to receive her.
