The density of cities in Pearl River Delta is very high.
The current position of “深圳 Shenzhen” is too “south” and should be a little bit “norther”. The font level of “深圳 Shenzhen” should be the same of “中山市” & other cities in that area, and, should be equal to or lower than “香港 Hong Kong” / “澳門 Macau”. For Hong Kong / Macau, suggested to display the full name by adding “特別行政區 Special Administrative Region” whenever possible.
