A literal translation of the sign in Mandarin should be "Beijing Camera Factory Sales Third Devision" or "Third Branch".

There are two mistakes. Firstly, a grammar mistake, it should be wash instead of washing. Secondly, 其他物品 means other items. In this case the sentence should be "Please don't shampoo and wash other items".
http://www.flickr.com/photos/davidfeng/3198847144/in/pool-chinglishA better way of phrasing the instructions are as follows:
1. Photo and Video taking is not allowed. (The message in Mandarin forbids both photo and video taking. This was not reflected fully in the English version of the message.)
2. Please look after your toiletries. (Advert is a direct dictionary translation of the word 注意. 注意 means to look after or be careful. Advert, on the other hand, means to turn attention to something, and has to be used with to: "advert to". Toiletry refers to one item, but people may bring more than one item of toiletry around, so toiletries in plural form is more appropriate.)
3. Please look after your beverage. (Beverage is a better word instead of drink.)
4. Please keep clean or Please be neat.
5. No smoking or Please don't smoke.

Please keep cleaning non-stop!
The sign should be "Please keep clean" instead.
http://www.engrish.com/page/55/The first sentence is a title, thus it would be better to capitalise the nouns: "The Environment Policies of Wujiang Jingsi Garden". And also, Wujiang Jingsi Garden is the name of the place thus it is a proper noun, and has to be capitalised.
The second sentence should say: "Protect the environment. Starting from me and from our garden." One cannot protect the envrionment from a person or from a garden.
