In our daily life, we often encounter some "good and bad" things, such as some merchants with indistinguishable personality, some products with uneven quality and so on. For such things, we should be vigilant, make wise choices as much as possible, and avoid our own losses.
At the same time, there are also some "good and bad" problems in society. For example, some politicians or company brands have lost their credibility for various reasons, causing social dissatisfaction and resistance. At this time, we should consciously reject these unhealthy phenomena, maintain our independent thinking ability, adhere to correct values and codes of conduct, and maintain the pursuit of justice and truth.
In this complex and changeable era, we need to be more aware of the harm of "good and bad" and keep keen observation and thinking ability at all times, so as to remain sober and rational in the complex social environment, and at the same time better understand, respect and cherish the real good deeds.
