1. How people in the past conveyed information
Do you know the story of the first mailbox?
In 1488, a fleet led by a Portuguese navigator named Dias was in distress at sea. Except for the ship he was on, all the other ships were destroyed and the whereabouts of some crew members are unknown. Before Diaz returned, he ordered his men to write a letter to his compatriots who might have survived, put it in a boot, and hung it on a dead branch by the sea. A year later, another Portuguese navigator, O. de Noir, passed by here and unexpectedly "received" the letter in the "mailbox". Therefore, a small church was built locally to commemorate the victims. Over time, a village sprang up near the chapel, and the story of the "postbox" became legendary. Since then, Portuguese sailors have been using the "postbox" made from this shoe to deliver messages, and the form of using the postbox to post letters has also been passed down. The emergence of the postbox has been recorded in documents in Paris, France in 1653, which is the earliest written record of the postbox. In 1852, the British set up the first postbox in St. Helier, Jersey. It is still in use today and can be regarded as the oldest postbox.
