Thanks @Pogo , for let me had idea about orbital plane. Since international space station's orbit inclination is 41 degree, so its orbital plane is more toward to earth equator. Hence Dragon Crew needs fly longer way to catch space station.

Dragon Crew spaceship needs almost 22 hours to arrive International Space Station. While Chinese spaceship does about 7 hours to arrive their space station. Why? Actually International Space Station and Chinese Space Station have similar orbit hight and speed. But orbit inclination is about 51...
