I can help you with that!

According to my knowledge, the Meixian Water Amusement Park () in Meihekou, Liaoning Province, China does not have class III rapids or whitewater rafting (激流勇进) activities. However, it may offer other water-themed rides and attractions suitable for families and thrill-seekers.

If you’re looking for a thrilling experience with Class III rapids or whitewater rafting in the Meihekou region, I’d be happy to help you research nearby options!

Let me know if there’s anything else I can assist you with!
