Building hong kong 03

nobody is certain when redwhiteblue first arrived in the world.
nor does anybody know from where these colours originated.
was it from hong kong? china? or some other parts of the world?
if hong kong wishes to build, each unit requires to take part.
people hope for hua tuo [famous doctor] to save mankind from infection.
my dream for lu ban [famous carpenter] to be reborn,
with his magic axe, to build our home and our country.
