What did the composition learn from the things around you? 100 words

Everyone will realize some truth from the things around them, and I have also realized some truth by observing ants. This morning, my friends and I went to play basketball. On the way, we met a group of ants fighting with a mantis. Mantis is very big. At first, only a few ants went up and were defeated. Later, the ants changed their tactics, and a group of ants rushed up and finally defeated mantis. From this incident, I understand that unity is strength.
