I didn't catch up with the flight time, but I felt better. At the end of December, I rushed past in the middle and afternoon of winter. There were very few tourists almost equal to the chartered venue. There were a small number of red-crowned cranes walking outside in the entire nature reserve, and there were many different kinds of birds. It is very beautiful at sunset at 3 o'clock and 4 o'clock, which is the feeling of the nature reserve in the imagination. Although it did not catch up with the release time, since it is a nature reserve, why do you need manual intervention to fly? Looking at the photos I took more than the same red-crowned crane flying in Trip.com reviews. iPhone X took it casually, no P picture.
