Before my crazy grandfather died, he gave me three walnuts. On my twenty-fifth birthday, I smashed the first walnut according to his last words. Inside was a note: Go under the overpass and kowtow three times to the first beggar you meet. My cheeks burned, but I did it anyway, and it turned out that the beggar was an undercover police officer. Later I found out that I had already been targeted by human traffickers, and kowtow saved my life.
