When you start taking the elevator, there will be ups and downs, which means you will have ups and downs in the future. The result of your dream is that you die, but the result of your dream is often the opposite, which means that you will get a better result in that matter, not a good one. Hot hands show that you can get help from others in the whole process of this matter to help you tide over this ups and downs.
The final road and white car show that the final result is smooth.
