1. Impact of the epidemic: The new coronavirus outbreak has had a considerable impact on the restaurant industry nationwide, including the takeout industry. During the outbreak, many people chose to isolate themselves at home or avoid gathering, leading to a drop in takeaway orders.

2. Weather changes: weather changes can also have an impact on takeaway orders. For example, in severe weather conditions such as heat, rain and snow, people are more likely to order takeaway at home with home-cooked food instead.

3. Policy adjustments: Government departments have introduced a series of regulatory measures and policy regulations for online food ordering platforms and delivery companies, and have strengthened enforcement efforts. These initiatives may cause certain businesses or platforms to be restricted or penalized and reduce their operations.

4. Market competition: There are many online food ordering platforms and delivery companies in the Hangzhou market, and there is fierce competition among brands. If the quality of service of certain brands is poor, the price is too high and other issues, it may lead to a decline in the number of orders.

It should be noted that the above are only some of the reasons that may lead to a decrease in takeout in Hangzhou, and they do not represent the whole picture. The specific situation also needs to be analyzed in conjunction with the actual local situation.
