[Movie] This Famous Medieval Book May Be a Hoax

[ReneZ]

Sure.  But here is what the dictionary says about the first function word of Mandarin that I picked at random with Google,

1. along [preposition]
   
   
2. to follow (a line, tradition etc) [verb]
   
   
3. to carry on [verb]
   
   
4. to trim (a border with braid, tape etc) [verb]
   
   
5. border [noun? adjective?]
   
   
6. edge [noun]
   

I know from the Thai language that many prepositions are actually verbs. 
Many words can be used either as a noun or as a verb, with related meanings.
Classifier words are very often nouns themselves.
Adjectives can sometimes be nouns or verbs.

Compared with European languages, the grammatical rules appear far more 'fuzzy'.
Undoubtedly, this is also true for other East-Asian languages.

Edit: some of these things also happen in English.

Example: the word 'bargain' can be a noun or a verb, but if it's a noun there would usually be an article.
Asian langauges I know of do not use articles.

Past or present participles (verbs) can usually be used as adjectives, but this is clear in their forms.
Many East- Asian languages do not inflect verbs

Again: the main objection to the Chinese theory in my opinion is the historical context. From statistical considerations I see no problem.
