Since the beginning of this year, the Guangdong-Hong Kong-Macao Greater Bay Area has received much attention. Anbound believes that apart from the superior background of the basic advantages, the development of the area is actually facing the bottleneck of system integration. The soft environment such as the policy system in the Greater Bay Area has been described as "one country, two systems, three tariff zones and three independent currencies". In the future, the top priority of the strategic development of the Greater Bay Area will be breaking down the barriers of the administrative planning and management system in nine cities and two administrative regions; this is also the largest difficulty.
