What does Jack mean?

Dakar compares love to a spare tire. Even the spare tire in Man Woman is usually used when the goddess changes the spare tire. A spare tire is a small spare tire that is temporarily used to equip tires. There are more tragic pipes than jacks. Jack is the simplest lifting equipment, and the lifting height is less than 1 m. Example: A person suddenly contacts you and she/he is looking for a spare tire. I suddenly stopped contacting you. It is normal. You are just a spare tire. I contacted you again one day, which is normal. You are a good spare tire. Then I won't contact you, it's still normal, and there is a better spare tire than you! The relationship among pitch, jack, spare tire and spare tire is generally as follows: the pump turns to the top of the jack, the jack turns to the spare tire, the spare tire is the spare tire, and the spare tire turns to the joint.
