Fuman Building also rolled out several new dishes, which weren't exactly new. Previously, the signature dish of Fuman Building was called Four Joys Fortune Bag, which sounded nice but was actually quite similar to dumplings. Since Lin Yuan subsequently introduced dishes like Crystal Shrimp Dumplings and Siu Mai, the status of the Four Joys Fortune Bag somewhat awkwardly diminished. It was no longer as enticing as a signature dish should be; yet removing it from that status seemed a great pity, especially considering that it was this dish that established the fame of Fuman Building.
Therefore, Lin Yuan decided to recreate the Four Joys Fortune Bag, developing it into a culinary series. This series was collectively named Four Joys Fortune Bag and became the number one signature dish of Fuman Building. Of course, to emphasize the preeminence of the main restaurant, this series was not available at other branches.
