For e-commerce platforms like Shopee, setting up pre-sales is very necessary. First, pre-sales can guide consumers to place orders in advance, reserve holiday gifts or shopping lists, thereby increasing sales and revenue.

Second, pre-sales can help merchants and platforms better plan inventory and logistics, reduce order retention and delivery delays during the holidays, and improve user experience and satisfaction.

In addition, pre-sales can enhance user loyalty and reputation to the platform, and attract more potential users' attention and participation. Therefore, for important holidays such as the Chinese New Year, Shopee should conduct pre-sales to make the purchasing process more convenient and quick for consumers.
