In the arena, everyone has prejudices in their hearts. Even if there are decent people among crooked families, and there are dirty people among so-called decent families, the prejudice in people's hearts is always a deep chasm that cannot be crossed. Some of the people in this book were unable to love because of prejudice; some were unable to change their stereotyped image in people's minds because of prejudice; some lost their lives because of prejudice; and some ended up with their wives and children separated and their families destroyed because of prejudice.
The prejudices in people's hearts are like a big mountain, and we are just ants at the foot of the mountain.
