TOEFLE SPEAKING-Most impressive event, Spring Festival China

In China, the most impressive festival is Spring Festival.

On Spring Festival Eve, sons get back to their parents' houses with their sons and wives. Two activities are necessary for a family to celebrate Spring Festival Eve.

One is to making jiaozi. When making jiaozi, family members talk about events happened in the passing year to say goodbye to the passing year. And they will put coins in jiaozi secretly. They believe that people who get jiaozi with coins have good lucky in the coming year.

Another activity is to play firework. Ancient Chinese thought that big sound would frighten monsters away. Nowadays Chinese regard this activity as one of the most exiting and interesting moments they may share with family.

Without either of the two, Spring Festival cannot be perfect. Chinese people take family as the most important part in their lives, so they cherish Spring Festival, which provides them a chance to have family reunion.

You could be more descriptive. It's kind of like you are writing a list of the activities that happen during the festival. Go into detail about making jiaozi, and for someone who's never been to China and knows little about the festivals - I would say explain what jiaozi is. You mentioned you make it...so how do you make it? I would also say, if possible make it a little longer...I'm actually interested in your topic. So you've grabbed the reader's attention, just paint a clear picture for the reader.

It sounds awkward if you say sons twice:

On Spring Festival Eve, sons get back to their parents' houses with their sons and wives.
On Spring Festival Eve, people return to their parents' houses with their sons and wives. Two activities are necessary for a family to celebrate Spring Festival Eve.

Another activity is to play enjoy fireworks. Ancient Chinese thought ... most exiting and interesting moments they may share with family. (Let's add one more sentence, because this paragraph is very short.)

Without either of the two, Spring Festival cannot could not be perfect. Chinese people take family as the most important part in their lives, so they cherish Spring Festival, which provides them a chance to have a family reunion.---This last sentence is beautifully written! :-) Congratulations, I think you have mastered English.
