Mr.Manish Dahal, the rate is US$100 per day in China, the 6 months bank statement is required. As for the hotel reservation and other documents, if you have them, you can provide them, if you don't have them, you don't need to provide them. However, if the visa officer asks them when you submit the visa application, you have to provide them. Generally speaking, the visa notification form and the Visa recommendation letter from your company are the most important documents for visa application, if you have them, the bank statements, hotel booking and other documents such as your income, property, police report, ralationship, etc are not required, please provide the first four documents listed by Ms.Mia.
