When I was in high school, one of my classmates sitting beside me. His name is Chen Liang. It is the unforgettable person in my life.I reminded me my math only average at this time, but it was excellent and distinguished to calculate and solve mathematical questions. They often have excellent results. Of course, I wish I could reach him. As we talked all day, wondering how we could solve these difficult questions. He was so patient and kind to answer my silly thoughts sometimes. Gradually going to build my confidence in mathematics and eventually adopted by the college-entrance exam.youthemeNow we’re apart, but I still remember the attitude and very willing to consider. I’m like, my classmates, an obligation that is my friend forever and ever.
