This tour is easy enough that you can return on time even if you only understand Chinese numbers. It's a shame not to understand the explanations of the places, but it doesn't significantly affect the tour itself. I didn't want to go to Rainbow Village, so I booked a Chinese tour through Klook. They picked me up at the hotel on time, and even provided simple guidance using Papago for Korean translation. They also took photos for us, and restaurant recommendations were available in the group chat. It was even more convenient that the guide sent photos via KakaoTalk. The weather was a bit disappointing due to rain and clouds, but if I come to Taichung again, I'd like to try it again. Umbrellas and water were prepared in the car, so I didn't need to bring them separately. However, the front seats of the 9-seater van can be uncomfortable for your legs and back, so if you understand Chinese, take the back seats. There's much more space. Even if your departure wasn't confirmed on Klook's date, it seemed like they combined bookings with other sites for transportation. Please keep this in mind when booking. I recommend it for its value for money and convenience of travel!
