The paper reconsiders the issue of betrayal in The Dream of the Red Chamber (especially mainly chapter 34). Traditional interpretation firmly holds that Aroma is the betrayer: her suggestion to Lady Wang is deemed as a betrayal and, it is claimed, results in the repelling of the waitresses of the House of Green Delights ( 怡紅院 ) . To re-examine this issue, I inspect both the psychological motif of Aroma's suggestion and the apparatus of the textual description of this event. First, I analyze the content of Aroma's suggestion, scrutinizing its layers and the logic of its development. Second, the textual description of the whole event is analyzed: it in fact utilizes a figural-recurrence apparatus. It is shown that the author designs and utilizes a lamp-image－which, from both archetypical symbolism and metaphorical implication, connotes illuming, enlightening, cleaning, and mirroring-to develop a parallel morphology between "lamp-girl" and "lamp knowing." Thus, I contend that there is no causal connection between Aroma's suggestion and Lady Wang's repelling the waitresses. There are many other characters qualified as the betrayer who induces the contraction of the House of Green Delights. I further delineate the rumoring network and the waiters-and-waitresses' personal nexus in the Jia family, thereby summarizing seven categories of people that may be relevant to the betrayal. Noticing and emphasizing the collectiveness of the information-transferral in the event of Lady Wang's repelling waitresses, I conclude that Aroma should be acquitted of the betrayal.
