Replying to [DrTim]:
Based on my experiences ,below are my personal ideas here .
U should choose Guangzhou as the third city for your business students 's international study trip Reasons are as follows:
a.Guangzhou is one of the most important city for import and export business in China .It is the true reflection of Word Famouse Factory and Made In China slogans here .
b. Canton Fair( www.cantonfair.org.cn) is the world's largest trading fair for all kinds of chinese products . It is held two sessions within one year and very famouse in the world business .
c.Guangzhou has hundreds of wholesale markets and also world famouse companies in town . Students could visit them in person and study the business culture in person .
d. Guangzhou ranks high status in China's economy and if you study Guangzhou deeply and you could understand china business perfectly
Just to be frank with your side ,I made one business presentation for Mexico MBA students in Guangzhou in May .Their ISP programme is very similar as your project here .Their business trip includes Beijing ,Guangzhou and Hongkong and Shanghai .
If you find we may chance to cooperate ,just feel free to let me know .
