Good afternoon , Mr . Yang . I'm Jill , Mr . Smith's secretary . Would you like to look around the factory first ?   Yes , I would .   Now this is our office block . We have all the administrative departments Sales , Accounting , Personnel , Market Research and so on .   What's that building opposite us ?   That's the warehouse where the larger items of medical instruments are stored . We keep a stock of the fast-moving items so that urgent orders can be met quickly from stock . ( in the workshop ) This is one of our three workshops . This is the delivery bay here .
