The Bronze Zodiac Heads of the Old Summer Palace — Ox, Tiger, Monkey and Pig — are currently on display at the Poly MGM Museum, which opened on Friday in Macao Special Administrative Region as the region will celebrate its 25th anniversary of return to the motherland on Dec 20.

Pansy Ho Chiu-King, chairwoman and executive director of MGM China Holdings Limited, said that the museum showcases over 200 artifacts spanning from the Tang Dynasty to early modern China, incorporating modern techniques, which will enhance tourism and also reflect Macao's moderately diversified economic development.

Reflecting on Macao's development over the past 25 years, Ho said, "I am indeed a witness, a participant, and one could even say, in this process, the greatest beneficiary of Macao's development."

"The achievements of Macao today are attributed to the expanded market, increased confidence, and the unwavering support of our country following our return," she said.
