Selling tobacco products to minors is a serious violation of the law and is against moral ethics, and there is no justification for it. Tobacco products are extremely harmful to the physical and mental health of minors, and the law clearly prohibits the sale of tobacco to minors. There is no so-called legitimate reason for this behavior "to investigate market demand", and it seriously violates the laws and regulations on protecting minors and the public interest. Any attempt to excuse this illegal behavior is unacceptable. We should resolutely uphold the dignity of the law and put an end to such illegal and criminal behavior, rather than trying to find inappropriate excuses to evade responsibility. We must actively cooperate with law enforcement agencies, bear the corresponding legal consequences, and at the same time deeply reflect on and prevent similar illegal behaviors from happening again to ensure a healthy growth environment for minors.
