If Hong Kong is your entrance in Asia for going into China, then you can
take the train from Hong Kong to Guangzhou to avoid the first unpleasant
part. Trust me, the road from Hong Kong to Guangzhou is NO fun. (see my
Hong Kong story).
You are able to board a direct train from Hong Kong to Guangzhou East
Railway Station instead of first going to Shenzhen and take a bus or train
Trains leave in Hong Kong at Hung Hom railways station in Kowloon. Some will
stop in Dong Guan.
