i would like travel to these cityes dongguan /changan town and shenzhen /guangdong and guangxi lizo

Are you sure the city yuu are going to Guangxi is called Lizo? I have been to Guangxi for four times, but never heard about it before.
You are suggested to start your journey from Shenzhen to Dongguan to Guangxi.
From Shenzhen to Dongguan, it is about 41 miles. You can take bullet train there from Shenzhen Railway Station, or you can go there by bus from those bus stations in the city.
I don’t know where is Lizo, so just give you some information to the provincial capital Nanning. From Dongguan to there, you can take train No. K1232 from Changping Railway Station.
Good luck!
