Having no hands on knowledge of car prices in China, or what the interest rates are for automotive loans/lease. Here is an hypothetical example of a car lease.
To simplify it, lets make a few assumptions.
Lease Term: 36 months
Type of Lease: Closed End/Walk Away
Interest Rate: 9%
MSRP: 100,000 RMB
Capital Cost: 100,000 on the assumption there is no discount from the dealer.
Capital Cost Reduction: 10,000 this would be the down payment plus applicable taxes to lower the capital cost from 100,000 minus 10,000 down
Net Capital Cost: 90,000 this is the starting amount for the lease.
Residual Value: 50,000 the residual value is calculated as a percentage of the MSRP, in this example lets use 50% 100,000 x 50%= 50,000
Depreciation: 40,000 this is the net cap cost of 90,000 minus the residual of 50,000
Depreciation / Month: 1,111.11 the total depreciation 40,000 divided by the lease term 36 months
Money Factor: Interest rate of 9% divided by 24 which gives a money factor of 0.09 divided by 24 = 0.00375 this is the factor for the monthly interest
Amount to Caculate Monthly Interest: Net Cap Cost 90,000 plus Residual 50,000 for a total of 140,000.
Monthly Interest: 140,000 x 0.00375 = 525
Total Monthly Payment: 1,111.11 depreciation + 525 interest = 1,636.11 total plus whatever taxes are applicable
