請高手幫忙改文法～

錯處:
1. Poly university, 冇左 "a/an/the" 同埋, 要寫全名
2. had succeed 的 tense用錯左, 用過去式已經可以
3. is total 1855 = 中式英文
4. the travelers of Mainland China of the data reflection collected purchases an ability the most high 完全唔知你講乜野, 無文法結構可言

***仲有好多錯不能盡錄, 歡迎 E-mail 我 ^_____________^


我的版本:::

The Hong Kong Polytechnic University was successful in visiting a total of 1922 people. There are 1855 valid questionnaires. The data shows that the mainlanders have the highest purchasing power, that is up to 53%. This also indicates that they would be more willing to spend money in attending tourist groups than the others. The tourists from mainland China had a global influence. They are also the main visitors in Hong Kong.
Therefore, we have concluded that the mainlanders are our market's target.
