It shouldn't be very difficult technically to expand the vote system from one pair of up/down buttons to multiple up/down buttons, elaborating the reasons behind the votes:

One pair for "very much on topic / very much off topic".

One pair for "I agree / I disagree".

One pair for "I dislike the poster / I like the poster".

One pair for "I have a bad day / I have a good day".

etc.

Then readers could filter posts according to that - for example if someone wants to only read comments that are on topic, allow them to only see posts that are "very much on topic", or at least exclude those that are "very much off topic".

Added benefit is that having multiple voting buttons would make life more entertaining for those who maybe just like to click things.

I have mentioned this often, but since opportunity arises here goes again.

We have a company doing service export, and in order to receive payments from foreign customers, we were required to have bank deposit or property in China to the value of maximum single transfer that we expect to receive.

For example, if we want to invoice foreign customer for 100 000 RMB, we would need to have equal sum already saved in China in some form.

The authority in question recommended to do like everyone else, and bypass these enterprise transaction requirements by asking the foreign customers to make payments to our personal bank accounts in China.

Asked about it from one of our foreign customers who had previously done business with other Chinese contractors. Was shown an invoice stressing the payer to very clearly mention that this payment is a personal transaction.

Not doing that, but I wonder how much tax evasion that comes down to in national scale.

I think the current recyclable vs non-recyclabe bins primarily serve to ease the burden of those elder people who collect recyclables of value. If only people didn't dump their left-over noodles in those bins.

If this worked perfectly, then the trucks and smaller vehicles collecting trash woudn't even have to empty those recyclable bins unless they're full.

As there currently is no recycling for organic waste at all, it requires some new large scale infrastructure to make it work.

If such would be managed by local government, it would be easy to just note from what xiagous such trucks arrive from, and fine the whole neighbourhood collectively if must.

For example in our neighbourhood (which is all houses managed by Junfa), it would then mean increases in annual management fees for all residents.

People would eventually start to look after their neighbours, and this is something where I think it is more justified than in some other areas.

There are no sorting regulations or recycling functions for organic waste in Kunming at all currently. Maybe some individual households outside the city use composting themselves, if they happen to have garden or such.

If we go back a bit, Shanghai started to implement regulations for organic waste just few weeks ago. They fine at least restaurants and other enterprises that fail to handle their organic waste properly - I'm not sure if they also fine individuals.

I don't know how the organic waste is treated in Shanghai past that. I do assume that if there are separate bins for organic waste, it is responsibility of the users to separate plastic and other recyclable material from from the organic waste prior to putting it in the bin.

My current information for Kunming (not to be trusted blindly), is that Kunming will implement similar requirements at the end of October this year. How much similar, I don't know.

So, for the time being there is nothing about

organic waste in Kunming.

Currently our organic waste goes to mixed waste, which then is taken for incineration. I don't know how much they sort it thereafter.

I don't frequent to places where foreigners gather (like ones mentionedy by Ishmael above), or generally mingle with other foreigners.

And my experience with this lifestyle is, that it's almost equally likely to meet someone from Africa as it is to meet someone from Americas or Europe.

In my own housing block of the (three) foreign faces I frequently see there is me from Europe, one guy from USA, and one guy from Africa. A few blocks away there seems to be a Russian family.

If I extrapolate from this neighbourhood across Kunming, and include all the students, then @cloudtrapezer's comment about 2000ish may not be far off.

Excluding students and temp visitors, I'd go for 500.
