Modern Chinese
樟脑球 are usually para-dichlorobenzene or naphthalene rather than real camphor (
从樟树 zhāngshù, the camphor tree, extracted). The name stuck because traditional ones were genuine camphor. The pungent storage-cupboard smell is iconic enough that
樟脑球味 is a literary shorthand for 'old-fashioned' or 'fusty'.
