When is the polar shadow day?

Shadowless Day is the solstice of summer every year.

On the solstice of this summer, you can see that the poles are gone in the tropic of cancer, such as Shantou, Guangzhou and Fengkai in Guangdong, Wuzhou and Guiping in Guangxi, Xichou and Mojiang in Yunnan. In Guangzhou, the morning time is 12: 29 from June 20th to 22nd (for three consecutive days). If the weather is fine, put the tall mineral water bottle on the horizontal ground a few minutes in advance at the gate where you live or work, and you can see the rare "shadowless pole" for three consecutive days.
