First of all, from a salary point of view, a monthly salary of 78 thousand dollars is considered to be a medium level in the city of Beijing. As a first-tier city, Beijing has a relatively high cost of living, so this salary level can guarantee the basic needs of life.
Secondly, the package means that an individual can save some of the cost of rent and meals. Renting an apartment and eating out in Beijing can be a significant expense, so a meal package can alleviate some of the financial pressure.
