How to identify the authenticity of this ceramic tile is as follows:

1. Look at the base trademark. The genuine product's trademark mark is clear, while the fake product's trademark mark is blurred.

2. Listen to the sound. The genuine one has a sharp and crisp sound, while the fake one has a muddy sound.

3. Weigh. The genuine product has a high density and is relatively heavy when weighed, while the fake product feels lighter.

4. Look at the packaging box. The manufacturer's address, manufacturer's phone number, manufacturer's website, product model, product color number, and production date on the genuine packaging box are all clearly marked, while the fake ones are very blurry.

5. Look at the ceramic tile body. Genuine Guangdong brick bodies are generally more delicate.
