The two upside-down 7s are Na Zhijie and Lexus logos. Na Zhijie is a transliteration of LUXGEN, which is a fusion of English words "Luxury" and "Genius". Na Zhijie's logo takes "L" as the main body, and it is also the deformation of the Chinese character "person", which symbolizes that Na Zhijie is based on it. On the whole, the logo of Lexus looks like an "L" letter surrounded by an ellipse, which comes from the initials of the English name of Lexus, and the ellipse carries the earth, meaning that Lexus is all over the world.
