What is the difference between Lenovo Zhaoyang K4 1-80 and ThinkPad E470 20h1001RCD?

Lenovo brand and ThinkPad brand. ThinkPad brand is bought from IBM, R&D team is still abroad, and there are many patented technologies. Brand values vary greatly. Lenovo brand focuses on cost performance, ThinkPad focuses on high-end. ThinkPad's T, X and W series are unmatched by Lenovo brands in terms of materials. Ordinary buyers only pay attention to the data in the configuration list. Although this understanding is intuitive, workmanship and materials are more important for such a precision device as a notebook. For example, Lenovo's commonly used engineering plastics can't compete with X250 aluminum-magnesium alloy, glass fiber and even carbon fiber A surface used in ThinkPad. It is directly reflected in the service life of notebook in normal environment. At the extreme, if you often squeeze the bus with a notebook, Lenovo will definitely be the first to scrap it.
