Why are road signs not in English?

The spelling rules of road signs are based on national regulations. The auxiliary text under the road name plate must be marked in Chinese pinyin and English cannot be used. For specific regulations, please refer to two normative materials, one is the "Design Code for Urban Road Traffic Facilities" and the other is "The Chinese Pinyin Alphabet Spelling Rules for Chinese Place Names (Chinese Place Names)".
