Generally speaking, the law and order there is ok, and the Filipino people are friendly, but you should take your passport with you in case of being checked.
3. Supermarkets, shopping malls and hotels in the Philippines are subject to security inspection, and private applicants are allowed to carry guns. So be careful not to go out as much as possible at night.
There are still many people in China, and you will often meet them. However, as long as you can speak English, communication in the Philippines is not a problem. It just takes a while to get used to it at first, because the English of Filipinos still has a strong local accent.
If you want to go to work, cook by yourself if you can. Philippine food is not used to eating, most of them are fried, which makes you feel bored easily, and eating too much is not good for your health, but the fruit there is good, and you can eat a lot of tropical fruits with very little money.
Besides, the climate is hot and humid, so you don't need to bring so many clothes. It's not enough locally, and it's not very expensive.
7. In the Philippines, you can easily find a foreign currency exchange shop. You don't need to go to the bank, but you'd better find a local friend to change it for you, because if you are a foreigner, you may sometimes change it into counterfeit money, or you can go to the front desk of a bigger hotel to change it, but the exchange rate is lower and there is a little loss.
