There are many units with great competition and limited places. If the comments are sub-high, it is generally safer to publish two cores. Of course, it depends on the specific environment of your unit. If the competitive pressure is not great, then publishing a Chinese core plus three or so general publications will be almost enough.
In addition, the core publications are basically scheduled for early next year. If you are preparing for next year, start as soon as possible. However, it should be noted that the core catalogue of Peking University 12 will be announced at the end of the year. If time is not in a hurry, we will arrange it after the new catalogue comes out at the end of the year. It's safer this way
