Who knows what kind of racing pigeons are suitable for flying in the mountainous area of 100~500KM?

Like our Quanzhou coast, there are many blood lines flying, and there are also 300-800KM races. Just like the Zhan Sen pigeon, the overlord of the sea, it doesn't fly very well along our coast, but once it reaches the northern plain, it flies very well. So racing pigeons also depends on the weather. Right place. Human nature is harmonious. I am also a pigeon lover, please contact me when you have time. Q: 99076 1 12 Quanzhou he pigeon industry
