We all know that the Chinese New Year will come soon and we will have several days off; so all of us help to tidy up the warehouse. And check the system stock and physical stock to ensure the consistency between the two. Firstly, we put all the yarns in order. Then, we mark every kind of yarn. And then, we clean up the warehouse. After this, we count the number of the yarn in warehouse and then check it with the system stock. Finally, if there is something wrong, we will find out the reason; and revise. Only doing this, we can quickly find and tell our customers how many kilograms the yarns they need are there.
