I remembered that I need to check the zones for Malaria in China.
I found this intuitive map:
One traveller recommended to get Malarone pills in the pharmacy and take them in malaria zones. They don’t have side-effects like other cheaper options (doxycycline and etc.), both will require prescription, but in my opinion long term antibiotics like doxycycline is more harmful and can cause more adverse effects to your body. Some anti-malarians can cause hallucinations, liver failure or even suicidal thoughts, so you have to be cautions and consult medical professional. Also not all antimalarials fit all the zones as malaria can be resistant to the drug, so you must consult with medical professionals that specialise in travel vaccination.
As it claims on the patient leaflet the adults should be taking 1 tablet per day and start 1-2 days before entering malaria zone and can take not longer than 28 days (apparently it is not very good for your liver and shouldn’t be mixed with alcohol). These tablets should be taken 7 days after leaving the malaria zone.
It is better to be safe than regret it later. I’ve heard malaria is really awful if you catch it and difficult to treat, so better to prevent it beforehand! Even though, when I arrived a health specialist in Sanya pharmacy said that you don’t need it in urban areas, just in the forests.
Apparently highly urbanised zones are safer due to pesticide use to control mosquitos, but all it takes one mosquito to contract it, so you have to make an informed decision either to take or not antimalarials.

Always consult your pharmacist or GP before taking any medication as this medication might not be suitable for you or outdated.
