Hong Kong Football Club and Tuen Mun were promoted from the second division to take part.
Citizen had to move away from its usual home ground, Mong Kok Stadium, due to renovations.
This season will be the first time in Hong Kong First Division League history that all 10 First Division clubs will be allocated their own sports ground for home games, without having to share with another club.
Double entertainment is a term meaning two clubs will play their home games on the same ground one after the other, to attract more fans and save costs.
Although both Sun Hei SC and Fourway Athletics would like to see the return of double entertainment, South China, Kitchee, Pegasus and Tai Chung are against it, while Tuen Mun's home ground do not have enough changing rooms to accommodate 4 teams.
