假如你是李华，你的美国笔友David准备组织一个“走进中国（Approach to China”的活动，他写信请你帮忙策划一下活动内容并介绍一下有中国特色的元素，以便让他的同学更好地了解中国。请你用英文写一封回信。
参考词汇：一带一路倡议 One Belt and One Road Initiative；吉祥物 mascot
I’m glad to know that you are launching a campaign “Approach to China” aiming to introduce your peers to a thriving China and be of some help.
From my perspective, the activities may range from Chinese calligraphy competition to paper cutting, martial arts, appreciation of Beijing Opera and so on. As for Chinese elements, the Great Wall with a long history symbolizes the national fighting spirits while high-speed railway representing the cutting-edge technology takes the lead in the world. China’s booming economy is marked with mobile payment and One Belt and One Road Initiative.
By the way, mascots like pandas and Monkey King will enjoy great popularity among participants.
Wish your campaign a success.
