In 1942, a German submarine sank a British merchant ship. A sailor of Chinese origin who served on it managed to jump overboard in a vest, and then found a free raft in the water. The small supplies of water and biscuits on the raft quickly ran out. The sailor, drifting on a raft in the Atlantic Ocean, collected rainwater and ate raw fish, which he caught with an improvised fishing rod, and once he managed to catch a seagull and suck its blood. 

So he swam for 133 days until the raft reached the Brazilian shore
