Need help from friends who are familiar with Shenzhen.

From Luohu Railway Station, that is, Shenzhen Railway Station, you can take bus 18 at the west square of the railway station (ask the staff or the police, Shenzhen people are very enthusiastic) to the Luohu talent market, and one more stop is the Shenzhen talent market, which is the most crowded place.

A safe and inexpensive house depends on how long you have lived. If you only stay for a few days, find a guest house, preferably the kind of office in Shenzhen of mainland provinces and cities. There are usually guest houses. The advantage is safe and clean, but the disadvantage is that the price is not very cheap for you who just arrived in Shenzhen. If you want something cheap, go to the so-called 10 yuan store. Generally, many people share a room, which is a bit messy and has no security guarantee. If you want to stay longer, you can rent a house nearby, which can be a single room in a suite (shared with others) or an independent small room with bathroom and kitchen. The specific price depends on the location you choose, ranging from 400+ to 600+/ month, but there is a deposit problem here, and you need to pay one month's rent and utilities in advance.

There is nothing special to pay attention to in Shenzhen. One thing you should pay attention to. You should take your certificate with you, and it's better to bring less cash. There is also looking for a job in Shenzhen. Both the deposit and the registration fee are fraudulent companies. Don't be cheated. And don't trust those "good people" who are particularly enthusiastic about you, and don't give anyone cash, including those who say they are hungry and want to have a meal. Do not believe! All the liars, none of them are true.

In short, going to Shenzhen is the same as going to any strange place, and the things that need attention are similar.
