On the Douyin e-commerce platform, merchants hope to attract traffic and increase sales by setting low prices for goods. However, low-price competition may attract the attention of the platform, so it is necessary to comply with the platform's rules and policies.

Here are some suggestions to help Doudian merchants avoid being investigated when setting low prices to attract traffic:

1. **Reasonable pricing**: Although the purpose is to attract traffic at a low price, the price of the goods should be reasonable and avoid being far below the market price to avoid suspicion from the platform.

2. **Limited-time promotion**: Use low-price activities as limited-time promotions, such as limited-time discounts, flash sales, etc., which is in line with normal business promotion logic.

3. **Quality assurance**: Ensure the quality of low-priced goods to avoid consumer complaints due to quality problems, thereby avoiding platform intervention.

4. **Transparent instructions**: Clearly explain the conditions and restrictions of promotional activities on product pages and promotional materials to avoid misunderstandings among consumers.

5. **Inventory management**: For low-priced goods, reasonably control inventory to avoid long-term backlogs, so as to avoid the platform thinking that merchants are maliciously competing at low prices.

6. **Compliance operation**: Comply with national laws and regulations and platform rules, and do not participate in any form of price monopoly, false propaganda and other illegal activities.

7. **Multiple strategies**: In addition to low-price strategies, you can also attract and retain consumers through various means such as providing high-quality services, innovative products, and interesting content.

8. **Data analysis**: Regularly analyze store data, including traffic, conversion rate, complaint rate, etc., to ensure healthy and sustainable business activities.

9. **Communicate with the platform**: If you are worried that low-price activities may cause problems, you can communicate with the platform customer service before the activity to understand the platform's position and suggestions.

10. **Monitor feedback**: Monitor consumer feedback and evaluation in a timely manner. If negative situations are found, take timely measures to avoid the expansion of problems.

Please remember that any business behavior needs to comply with rules and ethical standards, and low-price traffic strategies should ensure that they do not harm consumer rights and market order. Merchants should win consumer trust and market share through fair competition and providing value.
