i want a train from Hong Kong to Zhuzhou on a Monday. What are my options?

At Hung Hom Railway Station, HK, take a train to Guangzhou and you will be taken to Guangzhou East Railway Station, where there are T-trains to Zhuzhou and the duration of T-train is 6.5-7h. If you wanna take high-speed train to Zhuzhou, upon arrival at the East Station, take local subway line 1 to Gongyuaqian and transfer to line 2 to South Station to catch.
