And finally, people in Chifeng, Inner Mongolia, were treated to a rare sight on Friday morning, when three suns appeared in the sky.
周五早晨，内蒙古赤峰天空现奇观，出现“三个太阳”。

The real sun suddenly appeared to have two smaller twins, and was surrounded by rainbow-like halos. Some people even said they could see five suns. The meteorological bureau said the illusion is known as a phantom sun or ice halo.

真正的太阳周边突然出现两个“双胞胎”小太阳，而且被彩虹样的光环包围着。有人说甚至可以看见五个太阳。气象部门说这种幻觉为“假太阳”或“冰晕”。

It only appears when ice crystals create high clouds in the air around 6,000 meters above ground, reflecting sunlight.

在离地面约6000公里的高空中，云里面会有冰晶体，当这些冰晶体反射太阳光时，这种现象才会出现。
