Is BYD a Car for the Poor?

Driving a BYD does not necessarily mean the person is poor. Here is an introduction to BYD: 1. Brand History: BYD Company Limited was founded in 1995, starting with a team of just over 20 people. By 2003, it had grown into the world's second-largest rechargeable battery manufacturer and established BYD Auto in the same year. Originally a battery maker, BYD was essentially an 'outsider' when it came to automobile manufacturing. However, leveraging its 'independent intellectual property rights' and the acquisition of Qinchuan Auto, BYD gained a first-mover advantage over other newcomers. 2. Brand Introduction: BYD Auto adheres to a development path of independent R&D, production, and branding, committed to creating truly affordable and high-quality vehicles for the masses. Its product designs incorporate advanced international trends while aligning with Chinese cultural aesthetics.

Is It a Problem to Leave a Car Parked for a Week?

It's generally fine not to drive for a week. 1. Reduced lifespan: If a car remains parked for more than a week, it may shorten the vehicle's lifespan to varying degrees. 2. Battery and oil replacement: If the car has been stored in a garage for an extended period, it is advisable to visit a repair shop for a check-up on the battery, engine oil, etc., before reuse. Long-term parking can also accelerate the deterioration of engine oil, brake fluid, and antifreeze. 3. Performance check: Vehicles left parked for prolonged periods will gradually lose their original technical performance. Owners should regularly perform necessary maintenance on parked vehicles to keep them in good condition.

Why should the vehicle be circled counterclockwise instead of clockwise?

Because China implements right-hand traffic, vehicles are generally parked on the right side of the road. Drivers need to enter the driver's seat from the left side. At this time, conducting a counterclockwise inspection from the left front door ensures that the driver can see oncoming traffic and road conditions from behind, which is safer. Below are the precautions for the Subject 3 driving test: 1. Before starting the test: Circle the vehicle counterclockwise to check its condition. 2. After getting in the vehicle: Adjust the seat position, adjust the rearview mirror angle, and fasten the seat belt. Only after completing these steps can the test begin. 3. During all test items: Listen to voice prompts and do not act before the prompt. Special attention should be paid to the school and bus stop sections where there is no voice reminder. A deceleration and braking action must be performed within 30 meters, but not too early. 4. After completing the roadside parking: Do not rush to get out of the vehicle. Open the door, then close it, and only exit after the voice announcement of the results. Do not forget to close the door after getting out.
