The main front end writes a static page for a few days.

A joke: primary front end, 1 day to write 3 pages, intermediate front end, 1 day to write 1 page, advanced front end, 3 days to write 1 page.

Development is not a simple mechanical work, and the front end is not as simple as stacking labels. The ability of the front-end can't be defined by the number of pages, which is not quantified. Each page uses a different frame and way of thinking. No matter whether it is primary, intermediate or advanced, the number of pages produced cannot be measured by numbers.
