The NPC Standing Committee's interpretation of Article 104 of the Basic Law of the People's Republic of China (PRC) Special Administrative Region (the fifth interpretation) points out that public officials of the Hong Kong Special Administrative Region must "sincerely and solemnly swear" and read out "support the Basic Law of the People's Republic of China (PRC) Special Administrative Region and be loyal to the People's Republic of China (PRC) and People's Republic of China (PRC) Special Administrative Regions" accurately, completely and solemnly. Through the interpretation of the law, the National People's Congress Standing Committee (NPCSC) made clear the legislative intention of the oath, the solemnity and seriousness of the oath, highlighted the red line of the law, and solved the practical problems existing in the administrative region of Hong Kong, aiming at ensuring the real implementation of "Patriot ruling Hong Kong". It also shows that judicial independence under the framework of "one country, two systems" and the Basic Law should respect not only the power of Hong Kong courts to adjudicate cases independently, but also the power enjoyed by the central government according to law.

The history of the implementation of the Basic Law proves that the interpretation of the Basic Law by the National People's Congress is an indispensable legal mechanism to ensure that "one country, two systems" is not deformed or distorted, which shows that the ultimate guardian of the Basic Law is the central government. A very important experience in dealing with the relationship between NPC interpretation and judicial trial is to always adhere to the guiding ideology of "one country, two systems". "One country, two systems" is the guiding ideology of the Basic Law, the guiding ideology in the process of law implementation, and the soul of law. No matter the interpretation of the law by the National People's Congress or the judicial trial, we can't deviate from this idea.
