A senior official of the Hong Kong Special Administrative Region (HKSAR) government on Sunday stressed the education on the Constitution and the Hong Kong Basic Law to correct the misunderstanding of some people about "One Country, Two Systems."

The Constitution is not only the constitutional basis of "one country" but also serves as the legal basis and guarantee for "two systems," as the legislative basis and the source of effectiveness of the Basic Law, and as the cornerstone of Hong Kong's long-term prosperity and stability, Matthew Cheung, chief secretary for administration of the HKSAR government, said in an online article.

It is the shared responsibility of Hong Kong society to enhance the awareness of the Constitution and the Basic Law, act in accordance with them, and firmly uphold their authority, Cheung said.

Every Hong Kong resident should deeply understand the Constitution and the Basic Law and the relationship between "one country" and "two systems" and genuinely safeguard national sovereignty, security and development interests, as well as Hong Kong's prosperity, he said.

As Hong Kong has been pushed back on track since the national security law in the HKSAR took effect, Cheung said the government will continue to fend off and prevent acts endangering national security by means including various education, in particular school education.

On Friday, China's National Constitution Day, Hong Kong held an online forum to strengthen the understanding of Hong Kong society on the Constitution and the Basic Law.

Chief Executive of the HKSAR Carrie Lam addressed the event and described safeguarding the country's sovereignty as the "untouchable bottom line" for the implementation of "One Country, Two Systems" in the HKSAR. She also said that national security is a top priority for every country.

Luo Huining, director of the Liaison Office, also addressed the seminar, saying the implementation of the national security law has achieved initial results. 

Noting that Hong Kong is at a critical period to end the chaos and restore order, Luo called for concerted efforts from administrative, law enforcement and judicial sectors to implement the law.
