I don't think it's always a good idea for governments to use celebrities for health campaigns. Celebrities might not have the right knowledge to talk about health issues properly. There's a risk they could give wrong advice, which can be harmful. Also, people might focus more on the celebrity than the health message. Hiring celebrities can be expensive, and not all of them have a good reputation, which could hurt the campaign.
我不认为政府总是应该利用名人来进行健康宣传。名人可能没有正确的知识来恰当地讨论健康问题。他们可能给出错误的建议,这可能是有害的。此外,人们可能更关注名人而不是健康信息。雇佣名人可能很贵,并不是所有人都有良好的声誉,这可能对宣传造成伤害。
