From ancient times to the present, kung fu is an art full of practical skills. After a hundred years of development, there is no doubt that actual combat can definitely be practiced, but the level of actual combat mainly depends on the practitioner's own ability, how well he learns, how much actual combat experience and so on are very important, otherwise no matter how good kung fu may not be able to exert great power.
The so-called traditional kung fu has always been committed to actual combat results. The moves and playing styles in kung fu are all made from practice, which is down-to-earth and practical. Kung fu is not only the training of fists and feet, but also the flexible use of equipment. This is where the uniqueness of kung fu comes in, the moves are simple and brutal, full of power, one hit is instantaneous, and sometimes a single move can knock the opponent down. 
However, it is not practical to say that traditional kung fu is invincible in actual combat. From experience, the actual combat effect of kung fu is related to people's martial arts cultivation, actual combat experience, opponent level, and even venue conditions and competition rules. No matter how high your kung fu is, when you meet a real combat master or an advanced one, you still have to know how to judge the situation and adopt corresponding strategies and tactics. 
Therefore, it is no problem for traditional kung fu to be practiced, but there are too many factors that depend on the specific actual combat effect. In general, there must be actual combat ability in traditional kung fu, there is no high or low boxing skills, and those who practice martial arts are superior.
