3 . Don’t say “Cheese”, make a V!
V-sign is a common sight in informal, fun photos of people. It’s a gesture that says “I feel happy. Things are okay. Life is good. ”
In the West, the V-sign has an association with Winston Churchill. Churchill flashed the sign to stand for “Victory” to boost the confidence and cheerfulness of the British during World War II. This gave us the impressive gesture that is now known all around the world.
In Asia, the V-sign first became popular in Japan in the 1970s and quickly spread to China and South Korea.

5 . If you happened to find yourself in 17th-century Naples, you were in for a rough time. The Plague (瘟疫) of 1656 was in full swing. If you were one of the unlucky ones to come down with the disease, a visit from the plague doctor may have been in your future.
The plague doctors’ uniform didn’t exactly inspire a sense of calm. They wore a head-to-toe leather overcoat paired with leather gloves, boots, and a wide-brimmed hat. The whole outfit was modeled after a soldier’s suit of armor (盔甲). Fitting, when you consider that far more people died of plague than combat in the 17th century.
By far the most frightening part of the costume was the long-beaked mask, which marks an important moment in the history of the medical mask. The mask had thick glasses and two small holes in the beak (喙). The beak, stuffed with straw and aromatic herbs, was developed by the French medical doctor Charles de Lorme. It was among the first face coverings designed to reduce the spread of illness. Charles de Lorme developed the beaked mask based upon the theory of miasma (瘴气), an idea dating back to ancient Greece. The theory held that bad smells like that from rotting animal bodies or food, caused disease.
People in the 18th century understood that breathing in certain airborne particles and dust could be harmful. This eventually led Prussian mining official Alexander von Humboldt to invent a miners’ respirator in 1799.
Throughout the 19th century, doctors continued to go without masks while workers in factories were encouraged to use them to help filter (过滤) particle-ridden air. In an Irish flax-spinning factory, workers were said to have worn a “crape mask”. But when the British physician and writer Benjamin Ward Richardson visited the factory, he did not see a mask in sight. “Science…is conquered by free will,” he wrote, noting that until people “realize its usefulness”, the face mask “will have to wait”. And so, the face mask waited.
