How many times has the vehicle maintenance application been revised since it was submitted?

Twice. Applying for car repair refers to the monetary subsidy used as official transportation activities in the past, which was completed by other modes of transportation. It's the first time after submission. If the information does not meet the requirements or is incomplete, it will be revised twice and returned to the system for manual review. In addition, the number of places is automatically released, and the order is calculated according to the time of re-submission or supplementary submission.
