Have you ever tried hairy crabs? Do you know why they were being smuggled to Hong Kong? The video mentioned some illegal drugs. Why are they bad for us? If you found that your friend were addicted to drugs, what would you do? No, I had never tried hairy crabs. So, I didn't knew why they were smuggled to Hong Kong. The drugs are bad for us because they will cause harm in our body. If I found that my friend were addicted to drugs, I would first contact his or her parents about this, while I will also encourage her to consult a doctor and quit her bad habit of drinking or breathing in drugs.
