How should “Car” be understood in Car Seal Open and Car Seal Close?

2015-06-02View Original

Thread Content

CSC is the abbreviation for car seal close, meaning sealed shut with a seal. CSO is the abbreviation for Car Seal Open, meaning the seal has been broken. How should we understand \"car\" here?

car seal —— lead seal; you can look it up in the \"Youdao Dictionary\". For your reference

I’m talking about a car, not a car seal

\"Car\" means automobile. This type of seal was originally used to seal cargo cars; it’s an idiomatic expression that has been adopted from elsewhere
