Is "Lirengou" a trademark or brand name? If so, trademarks are usually protected by law. The purpose of trademark legal protection is to ensure that the trademark owner has exclusive rights to its logo in the market and prevent others from using the same or similar trademarks without authorization to avoid confusing consumers or infringing the rights of the trademark owner.

The scope of trademark legal protection includes, but is not limited to, the following aspects:

Trademark registration: A trademark owner can obtain legal protection by registering the trademark in the relevant country or region. A registered trademark provides the trademark owner with exclusive rights in law and enables it to pursue unauthorized use of the trademark.

Trademark infringement: If others use a trademark that is identical or similar to a registered trademark without authorization, it may constitute trademark infringement. The trademark owner can take legal action to require the other party to stop the infringement and may receive compensation.

Trademark rights protection: Trademark owners can protect their trademark rights by monitoring the market, discovering potential trademark infringements, and taking corresponding legal measures.

It should be noted that the specific scope and procedures of legal protection may vary from country to country.
