How to clip a mobile phone on a bookshelf with a book?

You can use the book holder mobile phone.

Whether reading, writing or playing mobile phones, the environment is too bright or too dark, which is easy to produce visual fatigue. Playing mobile phones in the dark for a long time will dilate pupils and increase intraocular pressure, which may lead to glaucoma in the long run, especially for people with a family history of glaucoma. Coupled with the child's soft sclera and elevated intraocular pressure, the eyeball will gradually become larger, and myopia or myopia will easily deepen.

Playing mobile phone in a meeting calls for improving the meeting style. The long and inefficient meeting process is related to the meeting content, meeting time and meeting quality. Some meetings are a mere formality, and relevant materials are sent in advance, which has little to do with whether the participants listen or not.

In some meetings, the speaker just follows the book, talks empty words and lacks substantive content, which is boring and even divorced from reality. To advocate changing the style of meetings, we should start with reducing the frequency of meetings and advocate short and intensive meetings. If the meeting is streamlined and the content becomes important and fascinating, no one will play mobile phones.
