Along the Beijing-Shanghai high speed railway, in a small city named Dezhou in east China's Shandong Province, the tomb of the East King of Sulu has stood tall for over 600 years. Sulu is an ancient kingdom located in the Philippine islands. More than 600 years ago, the Sulu King traveled across the sea to make political, economic, cultural and other exchanges with Chinese emperor Yongle in the Ming Dynasty.

As the Sulu King's lineage extends to more than 3,700 descendants in China, the tomb is also known as the only intact foreign king's tomb in the country. Join CGTN reporter Yang Xinmeng to explore the tomb and trace its history.
