Nowadays, science and technology in all countries are very developed, and many electronic products have been introduced, such as computers, mobile phones, especially mobile phones. There are many brands, just name a few, such as Huawei, Xiaomi, OPPO, Yijia, Nubia in China, Apple, Samsung, Nokia overseas, etc. But have you noticed that their mobile phone names all have suffixes, such as plus, Pro, etc.

Plus actually means "add", and this suffix is usually added after the name of Apple's mobile phone. For example, they'd better use one plus mobile phone, that is, iPhone6 plus, which is a little larger than their average mobile phone screen size. The screen of iPhone6 is 4.5 inches, while the screen of iPhone6 plus is 5.5 inches, which is still different in hand, and its storage will be larger than that of ordinary iPhone, so the price will naturally be higher.

Pro, many mobile phone brands have added this English word after their names, such as Huawei and Huawei P3 Pro. The English full name of the latter Pro is "professional". Friends who know English must know the meaning of this word. It means professional. Adding this Pro to Huawei's mobile phone name means that this mobile phone is more professional than their ordinary mobile phone, so the price will be higher than that of ordinary mobile phones.
