During the Spring Festival, because it is the peak season, the rent is usually 7 days or 5 days, and the price will fluctuate. You can find out if there are any outlets in your company such as Hi, Shenzhou and Supreme. These companies are generally at ease and the procedures will not be too cumbersome.
The landlord can also go to the "car rental online" to have a look, or call their customer service phone directly to help you find and recommend, and these services are free. If you are interested, just look around.
I forgot to mention my phone number. It's 057 1-89988338. Their company is headquartered in Hangzhou.
