The question of whether快乐 or忧伤 is the better choice is a topic that has been debated for centuries. While some people may argue that快乐 is the better option, others believe that忧伤 is more appropriate.
From a philosophical perspective，快乐 is seen as the better choice because it allows us to experience life in a more positive and enjoyable way.快乐 can bring a sense of fulfillment and happiness, which can help us to feel better about ourselves and the world around us.
However, from a practical perspective，忧伤 may be more necessary because it can help us to learn from our mistakes and to grow as individuals.忧伤 can also help us to be more empathetic and understanding of others, which can be beneficial in social situations.
Ultimately, the choice between快乐 and忧伤 is up to each individual. It depends on how they feel at the time, their values, and their goals. While快乐 may be more popular, it is important to remember that忧伤 can also be a necessary part of life, and it can help us to become more understanding and compassionate people.
