Does anyone know how many days it takes to go to Menyuan, Qinghai, what's the weather like in July, and whether there are flowering cauliflowers?

Three days is enough. It's cooler in July, so it's better to go in the middle of July. That's when rape flowers really bloom. I think it's up to you to organize a group or an individual. You don't know anything about it, and you don't often go out. You should organize a group to leave the ground. You can also go to Ta 'er Temple, cambra or something. Qinghai in July and August will make you wander back and forth.
