The Tet holiday is an exciting time, especially when you receive 'lì xì'. For many Vietnamese teenagers, this lucky money is the first significant amount they get to control themselves. Suddenly, you might have a wallet full of cash, or a digital balance on an app. The big question is: what will you do with it?

The choice can be difficult. It is very tempting to spend the money immediately on snacks, new clothes, or video games with friends. While these things bring short-term happiness, the money disappears quickly. The alternative is to plan and save. This requires discipline, but it opens the door to bigger and more rewarding purchases in the future.

Smart saving starts with a goal. Financial goals can be divided into two types. Short-term goals are things you want soon, like a ticket to a concert or a new board game. Long-term goals require more patience, such as saving for a new smartphone or a special trip. Using modern tools like e-wallets can help you track your progress and accumulate your savings more effectively.

Learning to manage your 'lì xì' is more than just about money; it’s your first lesson in financial responsibility. Developing good saving habits when you are young is a crucial step towards future financial independence. It teaches you the value of money and the power of patience, skills that will benefit you for your entire life.

The idea seemed simple: prevent all wildfires, no matter how small, to protect homes and nature. This policy, however, has had a disastrous, unintended consequence. Naturally occurring, low-intensity fires are essential for a healthy forest ecosystem, (37) __________. By preventing these small fires, fire suppression allowed this 'fuel' to build up for decades.

Now, when a fire does start, often ignited by lightning or human carelessness, it encounters an enormous amount of flammable material. Instead of a small fire that clears the ground, the result is a catastrophic megafire that burns hotter and spreads faster than ever before. These modern wildfires are so intense that they can destroy entire forests, (38) __________. Firefighters find these blazes nearly impossible to control, (39) __________. Therefore, experts now advocate for a new approach called 'prescribed burning,' which involves intentionally setting controlled fires (40) __________. This shift in strategy recognizes that fire, when managed correctly, is not always the enemy.

A. leaving behind a barren landscape that struggles to recover

B. to mimic the natural process and reduce the dangerous buildup of fuel

C. putting communities and ecosystems at unprecedented risk

D. clearing out the underbrush and dead plant material that accumulates on the forest floor
