English: COMAC C919 is China's first mass-produced "big" commercial aircraft. The project was launched in 2008 and is a direct competitor of the latest Airbus A320 and Boeing 737. You can easily distinguish it from the other narrow-body planes because it has only 4 canopy windows. This might be the first open-source printable C919 model. Compared to my previous Airbus A350 model, this one has more details. All parts of the model have been divided into multiple plates according to their color. Glue is needed during assembly. You can make it more realistic by applying liveries and painting it. I have a China Eastern Livery available at the bottom of the page.

中文：中国商飞C919是中国第一款量产的民用大飞机。项目立项于2008年并成为了最新一代的空客A320和波音717的直接对手。仅有4块驾驶舱玻璃是其最大的特色。这可能是全网第一个开源可打印中国商飞C919模型。相比我之前的空客A350，这款模型有着更多的细节。模型已按颜色进行分盘，无需多色模块。组装需要用到胶水。想要更真实的话可以上涂装和上色。简介末尾附带了东航涂装。

English: To make the winglets curved, heat them using a lighter to soften them and gently bend them upward.

中文：如果想做出翼尖小翼翘起来的样子，用打火机烤一下使其软化，然后轻轻向上折一下。
