Helping those who are in trouble is a good virtue, which one should treasure. Life is not all roses. No one knows when he or she will be in trouble. I think only by helping each other can we build a harmonious society. I had my personal experience. There was a time when Liming performed badly in my maths. It seemed that no matter how hard he tried, he still failed. Upset and disappointed, he fell ill and had to be in hospital for a couple of days. Hearing what had happened to him, I came to hospital , helping him with his schoolwork. It was with my aid that he recovered soon and improved himself in maths rapidly. He felt really grateful for what I had done. A month later, I met the same problem and Liming did the same thing to help me. From my experience above, I’ve learned that the sincere help between people is of great significance. Only with the care and help of others, can we get out of the difficulties in life .
