Legal basis, hehe, science and engineering students are really strange. Electricity needs a legal basis to pay the electricity bill. Then I'll tell you, the legal basis is equal resources, equal compensation, honesty and credit in civil law, and it is the payment consideration in contract law.
The sincerity of science and engineering depends on the liberal arts tree. I was shocked. When I use it, I ask you for water and electricity, and I want people to give you legal basis. ...
