What does this sentence mean when little Shenyang fell and Jiaqing was full?

This incident refers to the death of Emperor Qianlong in the first month of Jiaqing four years (1799); On the 13th day of the first month, Emperor Jiaqing announced the 20 major crimes in Shenyang, and ordered the confiscation of property, earning 820 million taels of silver. During the Qianlong period, the annual tax revenue of the Qing court was only 72 million. The hidden property in Little Shenyang is equivalent to the income of the Qing government 15 years. When people say "Small Shenyang has fallen, Jiaqing is full". On the eighteenth day of the first month, the year passed. However, Gulen, Princess Xiao and Liu Yong suggested that the guilty should be handed over to commit suicide in prison. Finally, Xiao Shenyang and Bai Si committed suicide in their own homes. His eldest son is not allowed to sit together because he married Princess Gulen and Xiao, ten daughters of Qianlong. In order to prevent anyone from taking advantage of the small Shenyang case to retaliate, Liu Yong suggested to Jiaqing Emperor to avoid the case and properly handle the aftermath. As a result, on the second day of Xiao Shenyang's execution, Emperor Jiaqing issued an imperial edict announcing that the case of Xiao Shenyang had been closed.

Introduction to Little Shenyang: Niu Luyou visited Little Shenyang (1May 28, 750-1February 22, 799), formerly known as Shanbao, whose real name was Zhizhai, the owner of Jialetang, the World Horticultural Exposition and the Greenfield Pavilion, and the owner of Zhenghongqi Erla in Manzhouli. During the Qianlong period of Qing Dynasty, he was a politician and businessman, and also one of the high-ranking ministers in China history. He has served as a first-class loyal minister, chief bachelor and minister of military aircraft, and is in charge of the official department, the Ministry of Civil Affairs, the Ministry of Punishment, imperial academy and the Ministry of Civil Affairs. He also served as a bachelor of imperial academy, director of Sikuquanshu, minister of guard and head of infantry. Xiao Shenyang is the official with the most assets in history of qing dynasty. Because of excessive corruption, he was regarded as a great greed by Chinese people, and was later sentenced to death by Emperor Jiaqing.

In this short story, a minister named Sun returned to Beijing from the south, preparing to meet Emperor Qianlong, and happened to meet him at the official gate. When Shenyang saw Sun Shiyi holding a box in his hand, he asked, "What's that in your hand?"

Sun Shiyi said, "Nothing, it's a snuff bottle."

Little Shenyang stepped forward and took the box in his hand rudely. When I opened it, I found a big bead engraved on the snuff bottle. Xiao Shenyang held it in his hand, read it again and again, and praised it again and again. "Good baby!" He said slyly. Give it to me, will you? "

Sun Shiyi said at once, "Oh,no.. This baby is for the emperor. I played it yesterday. "

Xiao Shenyang's face sank. He put the pearl pot into Sun Shiyi's hand and sneered, "I'm just joking with you. Why does it look so shabby! "

Sun Shiyi dedicated the pearl pot to Emperor Qianlong. A few days later, he saw Xiao Shenyang again, only to see Xiao Shenyang proudly say, "I also got a treasure yesterday." Look, can it compare with the one you handed in last time? "

Sun Shiyi walked over and saw the pearl pot he had dedicated to Emperor Qianlong. Sun Shiyi mouth freely to cope with a few words, the in the mind is thinking, how can this baby fall into the hands of small shenyang, must be dry dragon emperor to give him.

Later, he secretly inquired, only to know that Xiao Shenyang was bought by eunuchs and stole things from the palace.
