In the past 100 years, a discovery that really influence my life is the software 'Wechat'.  Scientists discovered it five years ago, as they wanted to figure out something to provide convenience for people's life. As all of the Chinese know, 'Wechat' is today's most popular communication app in China, it provides us free 'FaceTime function', to let us chatting with our friends online, at any time we want, even my friends and I are in different countries. Also, you can post your photos everyday, to let others know how is your daily life looks like. Others may comment and repost your post if they want to. Moreover, the funniest thing about this app is, you can call for food delivery to your home. It fits with the trend of Chinese people's living habit, most of them are too busy at work, so they don't have time to cook by themselves. Then, 'Wechat' will be a tool for them to get food quickly and cheaply. That's the reason why there are so many people using it in China. Finally, you can use 'Wechat' to call for taxi, that is common in China, since the people that are living in China usually don't buy a car. In that case, taxi is the best transportation tool for them. 

So I really appreciate the discovery of 'Wechat', and I love it so much.

          Fall is my favorite season in a whole year. There are two things that I like about fall.

         Firstly, when it is fall, the scenery of the outside natural world is fantastic. The leaves are turning red or yellow, and gently swinging down from the tree trunk. They are dancing through the wind as always. The pile of leaves that fell on the ground, is creating a enormous natural blanket. I love the feeling so much when I am walking on those leaves, it makes me closer to the nature and make me love those nature things instead of laying on my bed and watching youtube videos.

         Also, fall is the season that most of the fruit finish growing, especially my favorite food apple. They looks extremely red in the fall, and they are also extremely sweet, which fit my favor. When fall comes, my mum will buy plenty of fruit for me to enjoy. Also, we make a lot of apple pies when it's fall. It is my favorite dessert as it contains the fruit that I like the best.

 So that is why I like fall so much and the above things are what I enjoy the most.
