The national regulations for returns of fresh food are: if the two parties have not agreed that they can return or exchange goods without reason within seven days, then unless there is a quality problem, they cannot be returned. The Consumer Rights Protection Law only stipulates that if there is a quality problem, returns can be applied within seven days, and online shopping products have the right to be returned unconditionally within seven days; if the fresh food or services provided by the operator do not meet the quality requirements, consumers can return the goods in accordance with national regulations and the agreement between the parties.
