What are the road conditions and weather like driving back to Shaanxi during the Spring Festival?

Still optimistic, I recently took the Yin Fu Expressway from Wuhan to Weinan, Shaanxi. However, as far as these days are concerned, the climate change is quite obvious, and it is snowing, so there is a great possibility that expressway will freeze afterwards. Even if there is no obvious snowfall in those days when we return to Shaanxi during the Spring Festival, we should pay attention to it, because the pavement temperature in overhead areas such as roads, bridges and culverts is very low (ventilated up and down, without the protection of ground temperature), and there is frost, which is easy to slip. When to go back depends on the situation. It's not a big problem that expressway is not closed, but it's just a pavement like a continental bridge. You should slow down in advance, keep the steering wheel in the same lane, keep going straight at a low speed, try not to brake, and remember to brake suddenly. To avoid slipping and other accidents. Spring is still safety first. Go if you can. If you are in a bad state, you would rather stop and spend more time than take the risk of being too careless. Everything is going well at home, and spring is leaking!
