good, praise

臧 is composed of 爿 (bed, table), 臣 (official), and 戈 (spear, weapon). 爿 is a pictograph of a bed, 臣 depicts a wide-open eye, and 戈 represents a weapon with a long handle and horizontal blade. 臧 portrays a guard lying on a bed, with wide-open eyes and holding a weapon, remaining vigilant even at night without relaxing. This suggests the guard is protecting a place with highly valuable items. Thus, the original meaning of 臧 was to store or conceal, a meaning later taken over by 藏. Staying awake to protect valuable items indicates the guard is a virtuous person, worthy of praise, which is the meaning 臧 conveys today.
