CJK Unified Ideograph U+2A503

It names the wooden bar used to lift a ritual ding.

A ding (鼎) is a three-legged bronze vessel used in rites. The earliest dictionary account is in the Shuowen Jiezi, an Eastern Han dictionary: it defines the corresponding form as a wooden bar passed horizontally through the ding’s ears so it can be lifted.

Later dictionaries may gloss 𪔃 as 鼏, but the ritual distinction is bar versus cover. The Shuowen seal-script tradition also gives 𠕪 for this definition. In ritual writing, 扃 can name the lifting bar too; 鉉 is another related name, not the same character.

Someone sent me 𪔃—what should I read?

Read it as a reference to a historical Chinese character.
