The foreign name of Hoi Pian Hui "Papillons" comes from the French word "butterfly", which is a metaphor for the six buildings of the development being like three pairs of butterfly wings, dancing gracefully; while the Chinese name comes from the fact that it is built near the "sea" and is located on the south side of Tseung Kwan O. The riverside location overlooks the Lantang Strait and the East China Sea of ​​Hong Kong Island, "merging" the advantages of both sides of the river.

The project has a 4-story residential clubhouse with an area of ​​approximately 35,032 square feet. Its facilities include a 25-meter outdoor swimming pool, multi-functional banquet hall, mini cinema, fitness room
