people associate movie-watching and chatting with joy as they don't need to put any targets and pressure on these kind of activities. Meanwhile, human beings tend to associate study activities with pain as learning typically links to pressure; and naturally people do whatever they can to escape from pain.

是看那些活动能否带来快乐。如果寓教于乐能实现，学习一定也是很多人愿意的。可惜，考证考级的都不属于此类。
