"Temu" may refer to Pinduoduo's cross-border e-commerce platform Temu, and "not checking prices" may mean that the prices of goods on the platform have not been checked or reviewed. If the prices of goods on Temu are not checked, there may be the following reasons:

1. **System error**: There may be a malfunction or error in the platform's automatic pricing system, resulting in the price of goods not being reviewed according to the established rules.

2. **Operational error**: When the merchant puts the goods on the shelves, it may not set the price correctly due to operational errors, or forget to submit the price review.

3. **Price update**: The merchant may have adjusted the price after the goods were put on the shelves, but did not notify the platform in time for price review.

4. **Review delay**: The platform's review process may be delayed due to various reasons (such as holidays, system maintenance, insufficient review personnel, etc.).

5. **Policy change**: The platform may have adjusted the price review policy, resulting in some goods not needing to be checked temporarily.

6. **Special Promotions**: In some special promotions, the platform may allow merchants to set their own prices without strict price verification.

7. **Technical Issues**: Technical issues of the platform may also cause the price verification function to be temporarily unavailable.

If you encounter this situation, it is recommended to contact the customer service of the Temu platform to understand the specific situation, or check whether the product information complies with the platform's pricing rules. At the same time, merchants should ensure that all product prices are properly reviewed to avoid violating platform regulations or misleading consumers.
