Ask them to write you a dispatch letter, mainly to fill in some basic information, education and family background, and then take the dispatch letter to the current location of your file, Wuxi talent market. They will give you a registration card after taking the dispatch letter, and will not give you the file directly. At the same time, you should settle your file management fee. If you go to the talent market in your hometown with a registration card, they will automatically send the files from Wuxi to your hometown without going through your hands.
2. Regarding hukou, first of all, you should make sure that your hometown can accept hukou. In some places, such as rural hukou, it is difficult to transfer it back after you transfer it, because it involves land issues. If you can go to Wuxi talent market to open a registration card, he will tell you where your hukou is and give you a hukou certificate, usually at the local police station. You take the household registration certificate to the household registration section of the police station, and he will give you a household registration transfer certificate. There is a charge, but the exact amount is uncertain. All you have to do is go back to your hometown and re-register with your household registration card. Note that registration cards and household registration cards are time-limited, generally valid for one month. Don't delay, make several copies of your ID card.
The above is my real experience, I hope I can help you.
