What needs to be improved in the layout of urban identification system?

Lack or nonstandard English logo. With the communication in all aspects of the world, bilingual signs in Chinese and English are necessary, but most public signs in some places lack English signs. In a large shopping place, there is a "walk carefully when the road is wet", which not only uses traditional Chinese characters, but also has no English, which has no effect on foreigners who don't know Chinese. For example, the Shenzhen subway, although marked in English, is still Chinese. For example, the translation of "Beware of Meeting" on the elevator wall of Mixiang subway station is a big grammatical mistake. Mind is a verb, not an adjective. It should be changed to: Watch your head! It is wrong to translate the sign "Don't eat" into "Don't drink and eat". It should be changed to "or", otherwise it will be easily understood as "You can't drink but eat".
