If intelligence from other countries is collected privately without the consent of superiors, even if it is for the national interest, it may violate relevant laws and regulations. In many countries, intelligence collection activities are strictly regulated and supervised, and require authorization and approval from relevant departments and superiors. Collecting intelligence from other countries privately may lead to the following problems: 1. **Illegal behavior**: Unauthorized intelligence collection activities may violate relevant laws and regulations such as the National Security Law and the Counter-Espionage Law. 2. **Unintended consequences**: Collecting intelligence privately may lead to unexpected consequences, such as leaking state secrets, damaging the country's reputation, or causing diplomatic disputes. 3. **Lack of supervision**: Intelligence collection activities collected privately without the consent of superiors may not have an effective supervision mechanism, and it is difficult to ensure the accuracy and reliability of the collected intelligence. 4. **Personal risks**: Those who collect intelligence privately may face personal risks, such as being arrested, prosecuted, or punished in other forms.
