What is the relationship between the Hong Kong Legislative Council and the National People's Congress after the return of Hong Kong?

According to the Constitution of China, the National People's Congress is the highest organ of state power, and its permanent organ is the NPC Standing Committee (the Standing Committee of the National People's Congress). The Legislative Council of the Hong Kong Special Administrative Region is the legislature of the Region. It came into being in accordance with the Basic Law and the relevant decisions of the National People's Congress, which is fundamentally different from the nature of the Hong Kong-British Legislative Council as the legislative advisory body of the Governor. The Legislative Council of the SAR is a veritable legislature, which can enact, amend and repeal laws according to law. To examine and approve the budget according to the government's suggestions; Approve taxes and public expenditure; To hear and debate the policy address of the Chief Executive; Asking questions about government work; Agree to the appointment and removal of judges of the Court of Final Appeal and the Chief Justice of the High Court; And report to the Central People's Government for decision; Wait a minute.

According to the Basic Law, laws enacted by the Legislative Council of the the NPC Standing Committee Special Administrative Region must be reported to the Standing Committee of the National People's Congress for the record. Filing does not affect the entry into force of the law. NPC cannot unilaterally and directly legislate on the internal management affairs of the Hong Kong Special Administrative Region. Because the Basic Law stipulates that the Hong Kong Special Administrative Region shall enjoy legislative power, the Legislative Council of the Special Administrative Region shall legislate in accordance with the legislative procedures stipulated in the Basic Law. The NPC Standing Committee (the Standing Committee of the National People's Congress) consulted its Committee on the Basic Law of the Hong Kong Special Administrative Region on the laws enacted by the Legislative Council of the Special Administrative Region and reported to the NPC Standing Committee for the record. If it is considered that the laws enacted by the legislature of the SAR do not conform to the provisions of the Basic Law concerning the affairs managed by the central authorities and the relationship between the central authorities and the Hong Kong Special Administrative Region, the relevant laws may be sent back without any amendment. The law sent back by the NPC Standing Committee is invalid immediately. Unless otherwise provided by the laws of the Hong Kong Special Administrative Region, the invalidation of this Law shall have no retrospective effect.
