Only a couple drifted for a few days and arrived at a beautiful island. The islanders picked a fruit for them to eat, and they quickly recovered their strength and never wanted to go home again, where they married and had children. Later, people named this fruit "durian", which means "lingering". Zheng He, the eunuch of Ming Dynasty, led the fleet to the Western Ocean three times. Many crew members are anxious to return because they have been at sea for too long. One day, Zheng He found a bunch of strange fruits on the shore. He picked them up and tasted them with everyone.
