I wish Beijing leaders have a chance to read the above two articles.
The following is a Youtube video clip entitled "Beauty of Hong Kong Protests" created by a 16-year old local resident named Markian, with the song "Imagine" as background music:-
"You may say I'm a dreamer, but I'm not the only one!"
A nation that has lost the power of imagination is a tragic nation indeed! China should be proud of Hong Kong students for their creative thoughts and actions and stop smearing their honest and righteous motives.
