I followed the tour guide to his tomb, and suddenly my heart ached. It was the tomb of Liu Xiu, the orphan of the former dynasty who lived for 62 years. I held the monument, and my heart suddenly kept shaking. I was so trembling that I didn't even hear a word of the tour guide. It was said in the TV series that he led the troops to revolt and founded the Eastern Han Dynasty. The sky in Beijing was cold and damp. I leaned on his cold tombstone, without any warmth, but the tears kept flowing. It might be the wind, it might be the insects, but why does my heart hurt so much?
