Small Seal Script
Standardized 221–206 BCE (Qin); developed earlier in Qin
The standardized seal script promulgated after Qin’s unification, based on earlier Qin seal forms and used as an empire-wide norm.Wikipedia ->
Clerical Script
c. 300 BCE–220 CE (emerged late Warring States/Qin; dominant Han)
A practical script that evolved from late Warring States/Qin writing; it matured and became dominant in the Han dynasty, favoring faster, more rectilinear strokes.Wikipedia ->
