Central Inscription

The four large characters, read from right to left, are: 

澤及高陽

Literal Translation: "Favors (or blessings) reaching the high sun."

Contextual Translation: "Blessings reach the Gao Yang lineage"

Cultural Context: This is a poetic expression of gratitude. It signifies that the benevolence or blessings received are as vast and far-reaching as the sun's light. 

"Gao Yang" is also a significant ancestral place name (choronym) for certain Chinese clans, particularly the Xu (許) family.

Left Side (Dedication): 沐恩弟子許高陽堂敬送 

Translation: "Respectfully presented by the grateful devotee (disciple), Xu of the Gao Yang Hall."
