Hi Lodewijk

Yes we do find the lists on state and regional level. The reason we have to make a list is that there are still many different government-published list system. It may necessary to combine all of them to make it easy to find and to numbered.

So considering the current situation, is that means we don't really need to make a database for any using but only set some lists and unique ID?

You're not the only country struggling with this. Take for example the Netherlands. We have three systems: Rijksmonumenten (country level), Provinciale monumenten (province level) and Gemeentelijke Monumenten (municipality level). Rijksmonumenten are quite easy because every Rijksmonument gets assigned an unique id by the RCE (the government subsidiary that decides about this) so we just used that.
We haven't really implemented the Provincial level yet, so I'll just skip that. For the Gemeentelijke Monumenten we had a problem that many countries face: Every municipality has it's own numbering scheme. To solve this we used the principle of namespaces. In the Netherlands every municipality gets assigned an unique id. We combine this municipality id with the local id like <municipal id>/<local id>, for example 0392/59-0436 is https://commons.wikimedia.org/wiki/File:Voorgevel_van_winkelpand,_dubbele_etalage_met_portiek_in_het_midden,_hardstenen_omlijsting_met_decoratieve_bovenpui_-_Haarlem_-_20400391_-_RCE.jpg

We use / as the separator because that makes it easy to do funky template logical like showing the right municipality.

Going back to your original questions.

1. Unique ID: It seems many countries have their official IDs excluding China, or at least is non-published. Since it might hard to cooperate with government in this country, can we crete our own id for monuments in China? And are there any requirements for the Unique ID?

See my previous explanation. See what you can get, see if you can organize it with namespaces to keep it unique. Creating your own unique id is a last resort because it violates https://en.wikipedia.org/wiki/Wikipedia:No_original_research

2. List: The monuments list is needed. But I also found a page introducing database something like that, and seems complicated. So is this also necessary or we only need to make some lists instead of database.

If you make lists using templates a robot will pick up the data and put it in the database making all the shared tools also available for China. Please take a look at https://commons.wikimedia.org/wiki/File:The_secret_flow_of_Wiki_Loves_Monuments_infografic.svg and https://commons.wikimedia.org/wiki/Commons:Monuments_database#Structured_lists

Hope this helps
