Dhvaja was an ancient Buddhist stone inscription, which was originated in the Tang Dynasty. Several carved stones are piled up to form a column with a cap atop and Dharani scriptures and joss carved on the body. The 800-year-old Stone Dhvaja is the oldest antique in the Ancestor Memorial Garden and the only existing historical evidence of the emigration in the Ming Dynasty. The 9.4-meter-high Dhvaja is made of bluestones with octagon flats, extending 15 tiers in 4 layers. As a quintessence of engraving art of the Jin Dynasty, it boasts simple but sophisticated carving art, vigorous and fluent calligraphy and lifelike relief.
