Problem: I took this photo from an archaeological catalog; it’s a bamboo slip that records dietary principles regarding 'Qi.' Because the Clerical script (Lishu) has such heavy calligraphic brushwork—particularly in the first two and the last three characters—I’m struggling to identify them accurately. Could you help me recognize all nine characters on this slip and write them out in Simplified Chinese in their original order?
