The abstract drawings are required to be clearly identifiable when reduced to 4CM*6CM, but the so-called clear identification standard is not clear. This can be communicated with the examiner. If the structure shown in the drawings is too large and difficult to identify when zoomed out, you may consider supplementing the drawings in the original description with partial enlarged drawings showing the patented technical solution. This point is mainly decided after communicating with the examiner. You can propose to the examiner like this.
