In your example there would be one tag for location which would be, for example, china>Beijing>Tianamen Square then a second for content which would be People>General Candid with maybe a third for Content which could be Urban>Street Scene
Keywording is largely a subjective matter as one photographer would need or want to include certain keywords that are irrelevant to another. Whilst an ethnophotographer would find it useful to have keyword sets for ethnic origins, social groups, trades, community networks, etc; my going on holiday somewhere for pleasure would probably include the type of suggestion made by EOSAddict, at it's most elaborate.
In a nutshell: What way do you think; how would you think about it or go searching for it in the future; what's relevant to you?
Having said this, LR allows parent/child keywords, so the suggested above would be Parent, Child and Grandchild. LR can also export keeping this keyword relationship too.
The only trump I guess to 'making up' a keyword taxonomy that makes sense to you is if you do a lot of publication work, where the keywords would also help serve another orgainzation (client), in which case, when you've decided which route to take, be disciplined and objective in the keywording process.
IPTC carries structured data specific to the image, whilst keywords add context and depth to it.
