Chinese character 𰃍

Read it as a rare written form of 烘.

The Chinese character dictionary 《說文解字》 glosses 烘 as kindling or burning. 烘 also means warming or drying something with fire; by the Song dynasty, poems used it figuratively for making one image stand out against another.

A Ming sound-and-rhyme dictionary—a reference book that groups characters by sound—records 𰃍 in print between 1467–1471. That dates a surviving record, not the origin of the form.

Can I use 𰃍 in ordinary writing?

Use 烘 for ordinary modern writing.

Keep 𰃍 when preserving a historical source or discussing the rare form; 烘 is the familiar form for the everyday word.
