This is the flag and anthem that Mainland China should be concerned about. They are the flag and anthem of an INDEPENDENT Taiwan republic.
Mainland China and Mainland Chinese should NOT be afraid of the following flag and anthem. They are the flag and anthem of the existing Republic of China (ROC). In other words, the One-China Principle. So why are the Chi-Comms MAKING SUCH A BIG FUSS OVER PEOPLE WAVING THE ROC FLAG AND SINGING THE ROC FLAG ANTHEM (guoqige)?!
