I think renting a house is the most expensive thing to work in Shenzhen every month. Especially in some areas with convenient transportation, housing rents are relatively high. But living in Shenzhen requires renting a house. So I think we can find someone to share the house, so the rent and utilities will naturally be halved. You can save a lot of money every month.
In addition to the high cost of renting a house, the cost of eating out is also relatively high. So you'd better learn to cook by yourself. Usually cooking by yourself, eating out less will also reduce the cost of meals. And eating out and ordering takeout are more expensive, so you can't eat anything. So you might as well cook by yourself, which is cleaner, more hygienic and more delicious.
It would be better if your company has a meal supplement. If the company has a canteen, you can also eat in it. I think eating in is much cheaper than eating out, and it can also save a sum of money. I think the transportation fee should not be underestimated. Although the daily transportation fee is only a little, it costs about 100-200 a month, so if your company is not far away, you can choose a bicycle as your daily commuting tool. This can also exercise.
I think the most important thing to save money is to keep an account and record your monthly expenses. Then you will know what expenses need to be reduced. I think if we want to save money, we should buy less clothes and snacks every month.
