What are some factors that have contributed to a decline in mail volume over the past decades?

Iwill give all da points. imagine you are working for the u.s. branch of a chinese trading company. this trading company mainly trades chinese traditional art crafts and related items (such as chinese paintings and chinese music instruments). this week, your company had a promotion event, and a lot of goods were sold. now that the event is over, your manager asks you to write him a report in chinese. in this report, you are required to include: description of the chinese traditional art items being sold, their attributes such as colors and amount sold; price for each type of goods, and the total profit, in both chinese and u.s. currencies; your manager needs you to give an overall evaluation about what the most and least popular items are, and how people reacted to this promotion event – whether they liked this event or not. write as much as you can in chinese characters. it can be super simple btw
