When my eldest sister heard about a fainted boy, she also came to have a look. She found that I looked almost identical to her younger brother who had died in the car accident. Her heart stirred. She took me to see my father, and it was as if her younger brother had been reborn. My father's family had been passing on the family line with only one son for several generations. He doted on his younger son in every possible way on weekdays. The death of his younger son was a blow to him no less than another car accident. When he saw me, it was as if he had seen his younger son again. His body, which had been gradually losing its vitality, also perked up. Later, my eldest sister went through the adoption procedures for me. Since I was of a similar age to my younger brother and looked the same, everything like my name and birthday were borrowed from my younger brother's birth information. My father wanted me to inherit the bloodline of the Su family. Before he passed away, he held my eldest sister's hand and asked her to take good care of me as if I were her real younger brother. In fact, others had all persuaded my eldest sister and my father that they couldn't even take care of themselves, so how could they have the ability to adopt a child of unknown origin? But my eldest sister still took me in.

Since the car accident, there hadn't been much source of income at home. The family had been relying on the pensions from my parents' work units and the compensation for the car accident to make a living. On weekdays, besides taking care of my father in the hospital, my eldest sister also had to look after me and my second sister. She even had to take part-time jobs during holidays. My second sister and I were brought up single-handedly by my eldest sister. We had always led a hard life. I swore that when I grew up, I must earn a lot of money and repay my eldest sister well. In my heart, my eldest sister could completely take the place of my mother whose identity was unknown to me.

Although my eldest sister reluctantly gave up the opportunity to attend a key high school and entered a secondary vocational health school instead, she still didn't give up her aspiration for progress. With her academic performance, the courses in the health school were of course a piece of cake for her, and she got excellent grades in every subject. From the second year on, my eldest sister started to participate in the self-taught higher education examinations. She registered for four courses each time, which meant eight courses a year. My eldest sister was well-known for her intelligence. The secondary vocational school she attended had some basic courses that were not even as good as those in ordinary senior high schools. But she skipped several grades and directly studied the university courses. She chose the relatively simple major of accounting, which belonged to the liberal arts major and had not much connection with some science courses in senior high school. Therefore, she took the exams relatively smoothly. Only Advanced Mathematics gave her a headache, and she passed it on the third try. She attended classes at the health school during the day, went to the hospital to accompany my father at night and on Sundays, and also had to look after us at home. She could only study by herself when she had some free time. It was really tough, and she was always skinny. After starting to work, my father passed away, and my second sister and I were a bit older, so she had more time for study. Later, she successively obtained four diplomas, including a bachelor's degree in accounting, a junior college degree in nursing, a junior college degree in pharmacy, and a bachelor's degree in pharmacy. Moreover, she also passed the examinations and obtained two certificates, namely the Certified Public Accountant certificate and the Licensed Pharmacist certificate.
