The person managing these letters was named Lun Anguo, the eldest son of Lun Bing and husband of Jin Hongjun.
Recalling some things his father and wife had mentioned, and taking advantage of the fact that no second person had noticed, Lun Anguo decisively handed over the anonymous report letter to Cui Shaoyuan. Cui Shaoyuan and another staff member, after examining the letter, found its content to be a rehash of old issues about corruption and bribery pertaining to the Luo Family's gift-giving practices. The two comrades destroyed the letter on the spot.
Really, it wasn't as if Comrade Lu Jiang hadn't been investigated before. The Luo Family's gifts were given openly, a collective token of thanks from several families. Those who envied their more comfortable life resorted to this tactic without getting tired of it, huh?
