from guangzhou how do i plan my travel to dongguan city,zhangjigang,qingdao?

There are trains from both Guangzhou Railway Station and Guangzhou East Railway Station to Dongguan and it takes only half a hour. You mean Zhangjiagang in Jiangsu Province? It is about 1600km far away from Dongguan. There is no direct train and no airplane. One way is to take train from Dongguan East to Shanghai, nearly 18 hour. Then take bus from Shanghai to Zhangjiagang. Get to Suzhou and take train to Qingdao, which is another 17 hour trip.
