Inspired by the calligraphy on Chinese ceremonial bronze vessel inscriptions of the Zhou Dynasty (1066 - 770 BC) which are known as 'small seal' and characterised by their rounded strokes, these four Chinese characters form the classic four character phrase 英明文武 - the four noble virtues of an upright person:

英  Ying  Astute                                    明  Ming  Understanding                          文  Wen  Cultured                              武  Wu  Assertive

The Chinese language being a compound script, further meanings can be derived when different characters are paired together:

英明  Ying + Ming =  Brilliant              文明  Wen + Ming = Civilised                   文武  Wen + Wu =  Master of the Arts (cultural and martial arts)
