Within the system, core competitiveness is often not business ability, but:

Those with good writing skills, opportunities for promotion are very limited if you leave, who will do the work?
Those who flatter, can lighten the atmosphere, speak human language to people, speak ghost language to ghosts, provide psychological safety for leaders, have a high chance of promotion.
Those who can drink two jin of white wine, can boost the atmosphere at dinner parties, leaders like it, almost always bring you along to social events, have a high chance of promotion.
In the end, 💰 is still the most useful.
