If the demand for machinery in the city is fast, it will arrive in a day or two. The confidential rooms in Liuhe District and Jiangning District will take longer if they are not delivered every day. Secure communication is different from express delivery and EMS. Need to take a special channel for transportation, receipt and delivery must be signed and sealed, all kinds of records, so the time will be longer. Under normal circumstances, you can arrive at the file within 5 working days.
