Japanese people are very polite, but China people have a low status in Japan. It is impossible for the Japanese to accept you from the heart. But out of courtesy, it's good for you. My classmates are very sad about it.
There are still cultural differences between China and Japan.
Another job ... How can I put it? ...
Japanese consumption is also high. You have to speak fluent Japanese, otherwise looking for an intermediary is working in the workshop.
The agent deducted a lot of money from you. Unfortunately, everyone's situation is different. Please ask your friends again.
It's good if you're lucky. But unfortunately, if the factory closes or something, you will be in Shui Piao if you owe your salary.
One of the main reactions of Japanese workers is that China people bully China people. If your education level is not high, although you are in Japan, you will still be bullied by China people around you. If you do well, the Japanese will like you, and the China people will envy you or give you a hard time. Hey.
You are a boy. Remember that Japanese people are of high quality, but they are not really good to you (too little). It is always your parents who are good to you.
