Folk stories are handwritten to the fifth grade.

The folk stories I know are as follows:

Legend has it that in Xixia, there was a capital called Black Water City, where lived a monarch, who was brave and invincible and was called the Black General. He is the last monarch of Black Water City, unwilling to settle down and send troops to dominate. After the defeat, he fled back to Black Water City. The enemy surrounded the black water city and could not attack it for a long time. They saw the Ejina River outside the city passing through the city, so they blocked the upstream water source with sandbags and cut off the water in the city. The defenders of the Black Water City dug wells in the city, but after digging deep, there was still no water. General Black decided to lead his troops out of the city to fight. Before the war, General Black dumped more than 80 platinum cars and other treasures into the well, and personally killed his wife and children to avoid falling into the enemy. Subsequently, he led the army to war and was defeated and killed because he was outnumbered. The enemy invaded the city and searched the whole city, but found no treasure.

Since then, the story of the treasure left by General Black has attracted many people to seek treasure, but the whereabouts of the treasure is still a mystery.
