How is 'tomb' translated?

A direct translation in all versions. In Chinese, the word 陵墓 língmù 'mausoleum, tomb' sounds somewhat grander than 坟墓 fénmù 'grave, tomb'.

Note that the Vietnamese word mộ 'grave' requires a classifier, an example of the widespread use of classifiers/measure words in Vietnamese.
