Welcome to our factory .   I've been looking forward to visiting your factory .   Actually , you'll know our products better after the visit . I'll show you around and explain the operations as we go along .   That'll be most helpful .   Maybe we could start with the Design Department . And then we could look at the production line .   How much do you spend on design development every year .   About 10 % of the gross sales .   That's fine .
