We get wholemeal organic but we have to go direct to the farmer in Guizhou when we are there. I have no idea when we will return.

I think you can get whole meal bread four in Metro. If it is not whole meal, at least it will be course flour. You could then make your own, dead easy with a pasta machine.

Legal?
A cosh, but not a knife.

There is a thing called an Asp. It is like a telescopic baton, but metal. The police use them en.wikipedia.org/wiki/ASP,_Inc. . Usefull if you take some aikido lessons in how to use it. You see these around Kunming in the bird market and elsewhere.

Electrical things like Tazer may well be illegal.

Mace may be illegal. However, any perfumed spray, especially those with alcohol, will do the same job is sprayed in the eyes. Then run like hell.

Avoid anything potentially lethal or capable of causing grievous harm to anybody, because you won't be willing to use it. If you don't use it, it can be taken from you and used against you.
You don't need to harm people, you just need to get them to stop attacking you for long enough for you to run away.

As has been pointed out.
It is illegal for her to get pregnant out of wedlock. End of story.

Unless you want this child and see a future with this child, which is unlikely.
Tell her to go to the police, you will not pay a penny.
Don't do a paternity test, unless demanded by the courts. Otherwise you just make things more complicated for yourself.

If you do want a future with the child, which is unlikely to be permitted, then get a paternity test.

Unless you have other commitments here, go home to your country and leave not forwarding address.
If you are a teacher this is easy as you have no commitments after June. Wait till the dust settles and return to another city in China.

Sorry it this sounds brutal, but it does not sound like she is thinking about either you or the child, and she is probably being driven by the parents. She won't have the baby is the most likely occurrence. Her parents will probably take your money and then the girl will have an abortion. It will be impossible for her parents to marry her off if she has a child already.
Sounds heartless? This girl is not dealing with matters of the heart, she is blackmailing you.

The green stuff I am talking about that was taken off the market in about 1990 in EU was a green painted on wood treatment with a fungicide that was harmful to humans.

We got an H&S notice to handle any existing timbers with gloves and avoid other contact with exposed skin as it was taken into the body through the skin (adsorbed?).

That does not mean that other green product is not safe.

There is Anning hot water spa village just west of Anning. Thermal baths, some hotels not too expensive for a communal hot spring. Or more expensive if you want a spa bath in your room.

Very quiet mid week and some hill walking.
