This row has incomplete metadata: the pinyin field shows only 'liù' for a two-character word, and the POS label 't' is non-standard. Based on the characters, 陆月 appears to be the formal/financial way of writing 六月 (June), where 陆 is the capitalized form of the numeral 六 (used on banknotes, contracts, etc.). The correct pinyin should be liù yuè. Use with caution until the data is verified.
