Nowadays, especially in China, everything seems to favor social intercourse(社交) , such as gatherings of friends, KTV, group travel, dining tighter, playing cards and Mahjong, plus the Chinese-style " street-crossing group. "  Back home, discussions can still be boisterously carried on within the " circle of friends" of WeChat.

However,  these scenes cannot always ease a sense of loneliness. Zhu Ziqing, a well-known professor of Tsinghua University, signed with emotion: "My loneliness increases as scene becomes much busier. " One popular song today is also called " A lonely man in crowds. "  Actually,  engaging in social intercourse requires ability, while being alone involves the whole character.

These days, it is not easy to calm down totally and return to one' s true self. Willpower, intellect and discipline are required. Einstein said: "It is not your working time but your spare time that determines the possibility of whether you will be successful or not. " The "spare time" he referred to could be taken as " spending time by yourself. "

Lonely life could be either dull, boring and tasteless or abundant, interesting and colorful, depending on one' s quality, ambition and inspiration.

Just as the body constantly requires energy, the mind and soul also demand never stopping inputs. However,information, processed and integrated (融入) into knowledge, thoughts and feelings, instead of bustle  (忙碌)  seems to be the right condition. Successful careers m all walks of life worldwide have proved that "the soul grows in peace and talent is nurtured in loneliness". In a sense,  it may be reasonable to say that " Happiness tends to be shallow while loneliness involves depth".

Man, in fact, needs loneliness more than happy time, and only abundant loneliness can produce quality happiness.
