Susu reported the things given by Ruan Qiniang to the Old Madam and then took them back to her own room.
Four bolts of palace silk in fashionable patterns, four pockets, each containing a ring, identical to those given to the girls, presumably gifted by the Old Madam of Earl Annan.
A set of jewelry with a gold filigree inlaid with red gemstones, peony wealth pattern, consisting of sixteen pieces, was given by Ruan Qiniang.
Ruan Qiniang had specially hinted to Susu about the jewelry box containing this set. Susu carefully checked it and indeed found a hidden compartment with a letter from Ruan Qiniang inside.
In the letter, Ruan Qiniang explained the attitude of the Imperial Concubine at Prince Gong Mansion to Susu, telling her not to be afraid, and if there's no other choice, the last resort would be to reveal Susu's identity to Prince Gong, who, with his preference for peace over trouble, wouldn't report to the Emperor.
But this is really the last resort.
