Who can clean the throttle in Daqing Changsheng Auto Parts City?

Today, I went to the Jinlong Automobile Maintenance Center of Changsheng Automobile Parts City to change the oil and the three filters. Jinlong has been doing the daily maintenance and repair of my car. Before going to Xinjiang and Tibet, Jinlong helped me check the whole vehicle and chassis, and put forward suggestions on whether to replace brake pads, vibration reduction and other parts. Due to timely maintenance, although my car has traveled more than 220 thousand kilometers, it has basically not broken down. Vehicles, like people's bodies, need careful daily maintenance to work better, longer and more effectively.
