随着智能手机的普及和现代技术的发展，人们会在节日或他们的好友及家人过生日的时候，通过微信发送红包的方式来向他们的好友及家人表达他们的祝福，尤其是对那些在远方的好友或家人。

请写一篇短文来谈谈你的看法。

参考词汇：微信WeChat, 红包red envelope
精彩美文
With the popularity of smart phones and the development of modern technology, people will choose to send red envelopes through WeChat to their close friends or family members to express their best wishes when their family members or friends will have their birthdays or be at festivals, especially some faraway ones.
Compared with expressing their best wishes in person, expressing their best ones online have many advantages. Firstly, it's more convenient and quicker to send and receive them as well, without being limited by time and space. Secondly, they can also express their best wishes in words and pictures and so on, which is more interesting and lively. Most importantly, it also can save people much time especially in such a busy society.
In my opinion, I like this kind of wishes. I have to say it is just the Internet that is making our life more colourful and comfortable.
