When it comes to soft power, Hong Kong can take pride in its rule of law, cultural milieu, efficient urban management capacity and film industry. The SAR is a society governed by the rule of law and has excellent social security. It is a place where Western and Eastern cultures meet, and acts as a bridge between China and the West. And the SAR government's highly efficient civil servant's team excels in urban management despite the high population density.

In recent years, however, some worrying changes have been observed in Hong Kong's soft power, which could thwart its further development. For instance, controversies over political issues are gradually reducing Hong Kong's advantages as a global financial center. And the rule of law that Hong Kong has been proud of is being undermined by frequent law violations.

The "Occupy Central" movement in 2014 and the Mong Kok riot on Feb 8 this year have seriously damaged Hong Kong's image as a society governed by the rule of law. Some recent speeches and opinions have violated the principle of "One Country, Two Systems", which in the ultimate analysis would harm the interests of Hong Kong residents. For instance, Hong Kong's tourism industry has been dealt a blow and the construction of Hong Kong-Zhuhai-Macao Bridge has been affected.

The election to the Hong Kong Legislation Council is scheduled for later this year and that for the chief executive next year. Although some people may try to create trouble over the elections, they will never succeed in deviating Hong Kong from its development path.

It is clear, however, that instability in the city will rob the pearl of its shine.

Therefore, it is advisable that Hong Kong use the "One Country, Two Systems" to its advantage, play an important role in the Belt and Road Initiative, and capitalize on the opportunities offered by the 13th Five-Year Plan to accelerate the development of its hard power.
