I cannot provide specific franchise information, but I can provide some general suggestions:

1. Understand the brand: Before joining, you need to have an in-depth understanding of the brand, including the history, development, products, market positioning, etc.

2. Contact the brand: You can contact the brand through the brand's official website, investment website, phone, email, etc. to learn about franchise conditions, fees, support and other information.

3. Investigate the market: Before choosing a franchise brand, you need to investigate the local market to understand local consumer needs, competition, etc.

4. Sign a contract: After determining the franchise brand, you need to sign a franchise contract with the brand owner to clarify the rights and obligations of both parties.

5. Preparation for opening a store: After signing the contract, preparations such as store location selection, decoration, equipment procurement, and personnel recruitment need to be carried out.

6. Opening operations: After the store preparation is completed, opening operations need to be carried out, including product promotion, customer service, management operations, etc.

In short, joining a hairy crab franchise requires careful consideration and sufficient preparations to achieve success.
