Once upon a time, in a small village, there lived a man named Quang. Quang was always bragging about his skills and abilities, boasting that he was the best in everything. His neighbors had grown tired of his constant bragging, and they were skeptical of his claims. One day, the villagers decided to put Quang's abilities to the test. They asked him to construct a bridge over a nearby river, which had been a major obstacle for the villagers for years. Quang was happy to accept the challenge, claiming that he could complete the task in no time. Quang started working on the bridge, and the villagers were surprised to see that he was making progress faster than they expected. However, as days passed by, they noticed that Quang had cut corners in his work and they became worried that the bridge would not be safe. Finally, the day came when Quang declared that the bridge was complete. The villagers were hesitant to cross the bridge, as they were afraid that it might collapse. However, Quang assured them that the bridge was very sturdy and safe. To everyone's surprise, the bridge collapsed the moment the villagers started crossing it. Quang's claims were proven false, and the villagers realized that the proof of the pudding was in the eating. From that day on, Quang's bragging lost all credibility, and the villagers never trusted him again.
