1, first check whether these circled numerical serial numbers are included in the input method. For example, input: Wu → the fifth is the digital serial number (circled) that comes with Sogou Pinyin input method.

2. At this time, you have to do a custom phrase operation, because the system will save the circled digital serial number in the fifth place by default, which is still inconvenient to use. You need to press 5 on the keyboard again to display the circled numerical serial number on the screen. The steps are: enter Wu, then put the mouse up, click Add phrase, then select the fifth ⑤ and confirm. After entering Wu in this way, ⑤ will appear in the first position, and press the space bar to go to the screen.

3. However, at this time, we will find that the serial numbers such as ③ and ⑩ are missing from the system. You may want to use semicolon +F to bring up the symbolic encyclopedia, or click more special symbols to bring up the symbolic encyclopedia when the input field appears.

4. After opening, click the digital serial number.

5. In this way, the numbers circled from ① to _ are filled in pinyin phrases respectively. By default, it will be ranked first. When typing, press the space bar to get on the screen.

6. If you like the circled numbers, you can add more. The numerical serial numbers from _ to _ are listed below for users who need to customize the circled numerical serial numbers. You can copy them all first, then customize them, and then cut the subsequent serial numbers step by step until all serial numbers are customized. Some figures will be repeated, but the problem is not big, you can choose if necessary. ______________________________
