Sometime in February, my teacher told us about the city speech contest, its topic was “People who have overcome difficulties in their lives”. I thought of my grandma would be my perfect topic. Then I carefully prepared for contest. A couple of weeks later, after the first round I was choosing to be one of the seven finalists! The final was held soon. I was the sixth to presenting the speech. How a relief when I finished it! After the last person finished, the judge made their final decisions and announced that I have won first prize. The audience were going wildly clapping and cheering! I was extremely happy. It was such exciting a moment that I will always remember it.
