Sounds like a problem with your Idle Control Valve (ICV, 怠轉控制活門). You can try to have the shop to decarbonate it if it's just dirty. However, you may have to change a new one if it's too old or worn out. If your car is equipped with Mass Airflow Sensor (MAF sensor, 生氣/生風流量感應器), it may be the culprit also if it's dirty because the car's ECU/computer will use the MAF to calculate how much fuel to inject to the cylinder based on how much intake air the engine is breathing in.
