The whole expressway from Shenzhen to Kaili, Guizhou. Please elaborate.

In my experience, the best way from Shenzhen to Kaili is Shenzhen-Guangzhou-Shaoguan-Hengyang-Shaodong (about100km for the secondary highway with poor road conditions)-Huaihua-Yuping-Kaili. Fastest trip 15 hour, private car, eating in the service area along the way, and proper rest in the car. It is also said that the expressway from Huaihua to Guilin passed, but it did not. If you go to Guangxi, there are two ways to choose. One is Shenzhen-Guangzhou-Maoming-Beihai-Nanning-Wuming-Du 'an-Nandan-Dushan-Duyun-Kaili. Basically, the whole journey is high-speed, but the road is too far. 2. Shenzhen-Guangzhou-Yunfu-Wuzhou-Guilin-Liuzhou-Hechi (Jin Chengjiang)-Nandan-Dushan-Duyun-Kaili. The Guilin line hasn't passed yet. I don't know if it's faster. I often drive back to Kaili for the Spring Festival, and my experience is for reference.
