At about 6 o'clock in the evening of yesterday (4), the spectacle of lights in Hong Kong was seen everywhere in Hong Kong that looked like a symphony of colors chanting the Xiangjiang River.
It turned out to be the weather landscape "Twilight".
According to the Observatory's interpretation, "twilight" refers to the phenomenon of "crepuscular rays" that occurs at sunrise or sunset. It is mainly due to the sun's rays being blocked by clouds or mountains, forming light and dark rays that diverge.
