The time for placing an order on Pinduoduo's cross-border platform Temu is not a fixed time point. It is affected by many factors, including market demand, product types, pricing strategies, marketing strategies, and the platform's operating strategies. Therefore, it is impossible to give an exact time for placing an order.

However, in general, if merchants can choose hot-selling products, set reasonable prices, and conduct effective promotions, the speed of placing an order may be faster. At the same time, the platform's operating strategy will also have an impact on the time of placing an order. For example, the platform may conduct promotional activities regularly, which may bring more traffic and orders.

If you are a merchant and want to increase the speed of placing an order on Temu, it is recommended that you pay close attention to market demand, optimize product information and pricing strategies, actively participate in the platform's promotional activities, and continuously improve product quality and service levels to attract more consumers.

Please note that cross-border e-commerce is a highly competitive field, and success requires time and effort. It is recommended that you remain patient and confident, continue to work hard, and believe that your efforts will be rewarded.
