Ferdinand, a famous Portuguese navigator and explorer, sailed to Portugal (1505 ~ 15 12) and Spain (1519 ~152/) successively. Start from Spain, bypass South America, find strait of magellan, and then cross the Pacific Ocean. Although he was killed in the Philippines, his ship continued to sail west and returned to Spain, completing its first round-the-world voyage. Considered to be the first person to sail around the world.

Zhelun's outstanding contribution lies not in the voyage around the world itself, but in his bold belief and excellent command of this cause. He was the first person to cross the Pacific Ocean from east to west. It took him more than three months' voyage to change the popular concept at that time: it only takes a few days to reach East India by boat from the New World to the west. The practice of Magellan's fleet sailing around the world proved that the earth is a round body. No matter from west to east or from east to west, there is no doubt that it can go back to its original place once it goes around our planet. This will always be an indelible great feat in human history.
