The highlight of our project is was that we managed to achieve the internationalization of the respondents find respondents from a wide range of countries. We chose foreign students who come from different continents including Southeast Asia, Europe, America (/the Americas) and Africa, in universities such as Beijing Foriegn Foreign Studies University, Beijing International Studies University as well as Beijing Language and Culture University as and our respondents', whose answers have played (is the project still important to you now or are you talking about a memory from your past? If it's a memory from your past then past simple is better) an important role in the outcome of our project.
Our research shows that during through the process of overseas circulation of Chinese movies, we need to integrate more modern elements into the movie to show a civilized China with developed economy, cultural prosperity and good government to the world; to change the world’s inherent impression of that China which is poor and backward. We need to put more emphasis on the overseas circulation of movies that tell the story of Chinese modern life so that people from other countries can have a comprehensive understanding of today’s China, which is good for enhancing our country’s cultural soft power. Moreover,we also printed and gave out hundreds of pamphlets that introduce Chinese movie directors and recommend several excellent Chinese modern movies to the foreign students in Beijing to increase their interest in knowing more about modern China.

It wasn't totally clear who this text is written for.

- Is this a memory from your junior year about a project you worked on and finished long ago? If so, PAST SIMPLE is the better tense. This is usually the case when describing memories.

- Is this a project that you finished very recently, and will submit to your professor soon? If so, PRESENT PERFECT is better, because you're talking about a past that's very relevant to the present.

I wasn't too sure which was the case, so it was difficult for me to correct, however please take another look and if anything's unclear feel free to ask.

Your English is very good!

Introduction to my project (part 1)

In my junior year, I participated in the National Undergraduate Training Program and got subsidization a subsidy of about 10 tousand yuan. The topic of our project is was the overseas circulation of Chinese movie and the buildup of China’s national image, which is an inter-disciplinary field of research between communication and diplomacy.
As to the work distribution, depending on different stages of work, every member of our team would have the chance of becoming (/to be) the leader to allocate different tasks to other members. As for me, I was in charge of data aggregation and analysis. I would be responsible for making the detailed work schedule and arranging the tasks to the members during this period. Specifically speaking, I had to set a timeline for certain tasks including selecting effective questionnaires and inputting data into SPSS software. Besides that, I paid much (/a lot of/a large amount of) attention to the work of analyzing data by using (/through) SPSS software. Thanks to the knowledge what we learnt in our social statistics lesson (/course), we can could carry on out the chi square analysis on the SPSS software with less difficulty (/fewer difficulties).
