Red walls and yellow tiles tell the story of six hundred years of vicissitudes; and your voice gives history warmth. Thank you, Mr. Zhu, the top scholar from Beijing, for leading us through the morning light at the Meridian Gate, helping us understand the changing of imperial power under the eaves of the Hall of Supreme Harmony, and allowing us to hear the echoes of time between the bricks and stones of the Palace of Compassion and Tranquility. It wasn't a superficial visit, but a dialogue across time. Because of your narration, the Forbidden City is no longer an empty city, but an open history book. Next time I come to Beijing, I'll definitely ask you to be my 'time travel guide' again.
