Visual communication is a way for designers to show what they want to express through visual elements. For Yingying Cai, using visual communication to convey social information is what she persists to do.

Due to the period of big data, the dissemination of social information is becoming faster and faster, so that many things cause attention very soon. In her work <Time>, she photographed a lot of writing instruments at different times to raise awareness of the handwriting crisis. Nowadays, more and more people rely on high-tech software to translate words by voice, which leads to the frequent occurrence of character amnesia. The problem is especially acute in languages with many hieroglyphics, such as Chinese characters. She hopes to let people aware that handwriting is as important as the ease of using high-tech software.

In her another work <Unreachable>, she focused on some special allergic people because of her own allergy experience. 

These allergy patients are allergic to hair, but these allergies are often very popular for normal people, such as cute plush toys, delicious peach, warm wool clothing, etc. She visualizes these allergies to make normal people feel these reactions, so as to express the unreachable distance between allergy patients and these beautiful things.

For Yingying, vision is a more powerful way than any other methods to express and highlight some social issues, as well as to remind people of some neglected phenomenon.

視覺傳達是一種讓設計師通過視覺元素把想表達的信息進行傳播的途徑。對于蔡盈盈來說，她更執著于運用視覺傳達的方式傳遞社會信息。

由于大數據時代的到來，社會信息傳播變的越來越快捷，也讓很多事情被迅速引起了關注。在她的作品《時間》里，她為了引發人們去關注手寫危機拍攝了不同時期的書寫工具。現在越來越多人去依賴高科技軟件語音翻譯文字導致提筆忘字這一件事情頻頻出現。特別像是漢字這種象形文字偏多的語言這種問題更是突出。她希望讓人們意識到在運用方便的高科技軟件的同時不要忘記手寫也是同樣重要的一項能力。

在她另外一個作品《遙不可及》中，因為本身對花粉的過敏使得她注意到了一些特殊過敏人群。這些過敏患者都對毛有著過敏癥狀，往往這些過敏物對于正常人來說是十分喜愛的，像可愛的毛絨玩具，可口的水蜜桃，溫暖的羊毛衣服等。她把這些過敏物通過視覺表達讓正常人感受到這些過敏反應，從而去表達過敏患者對于這些美好的事物的遙不可及。

對于蔡盈盈來說視覺會比其他表達方式更加有力突出的去點明一些社會問題，并且能夠通過作品去提醒人們一些忽視的現象。
