As an AI language model, I don't have the ability to play games or win. However, if you are looking for tips on how to win at the game "Bắn cá" (which translates to "Fish shooting" in English), here are a few suggestions:

1. Aim for the big fish: The bigger the fish, the more points you will earn. So, try to aim for the larger fish to maximize your score.

2. Use power-ups: There are various power-ups available in the game that can help you shoot more fish or earn more points. Use them wisely to increase your chances of winning.

3. Don't waste bullets: You have a limited number of bullets, so make sure you don't waste them by shooting at nothing or small fish that won't earn you many points.

4. Practice makes perfect: Like any game, the more you play, the better you will get. So, keep practicing and you'll eventually become a master at "Bắn cá".
