Why do China fighters like duck wings very much?

According to the technical characteristics and design ideas of China, China designers prefer duck wings.

The advantage of canard is that it can generate vortex above the main wing and improve the stall angle of attack. The disadvantage is that it is easy to cause instability. For China's modern aviation industry, aero-engine technology is relatively weak, but electronic system, aerodynamics and control technology are relatively strong, and canards can make up for the lack of flight performance.

For American aircraft designers, another disadvantage of canard is that it destroys stealth, but for China, we consider that canard is mainly used for aircraft take-off and landing and close combat, because the altitude of aircraft take-off and landing is low, the stealth problem is not prominent, and close combat does not care about stealth ability, so we keep canard.
