an ancient Chinese province
鄭 refers to an ancient Chinese province. Its meaning is a proper noun without a broader conceptual center.
鄭 combines 奠 (possibly phonetic) with ⻏ (village/city), suggesting a place name. The exact historical development is uncertain.
The left side 奠 looks like a ceremonial offering, and the right side ⻏ is a village. Picture an ancient Chinese province known for its grand ceremonies.
For テイ, imagine a tea ceremony in that ancient province: tea -> テイ, and the province is famous for its tea rituals.
