Interesting story...
Once the Mongols were besieging a Chinese city. They captured a Chinese official coming to the city and took him prisoner. Subsequently, a Mongol in Chinese clothes entered the city pretending to be the official...and...surprise! the Mongol army got up and fled. The "Chinese official" congratulated the town's defenders on winning the battle and oversaw the dismantling of the city's defenses.
...once the defenses were all torn down, the Mongols returned in the middle of the night and by morning were swarming all over the city!
My ancestors for ya...
