IMO, this is the best answer! I think these words literally captures the sound of different kinds of laughter. I wouldn't be surprised if their equivalents exist in other languages.

<h1>呵呵</h1>
<p><em>Hehe</em> is the most general laugh, indicating perhaps just a smile. Its meaning is the most vague and in some situations can imply an embarrassed, self mocking, or even sarcastic laugh.</p>
<p><em>（Update: note the added caution that @shellbye gives in his answer about the meaning of this one. I suggest you keep observing its usage before using it too freely yourself.)</em></p>
<h1>哈哈</h1>
<p><em>Haha</em> has the clearest meaning. It's a great big happy laugh.</p>
<h1>嘻嘻</h1>
<p><em>Xixi</em> is mostly (but not exclusively) used by females and conveys a sense of mischievousness and lightheartedness. In certain situations it can even have an air of 撒娇. <em>Xixi</em> is perhaps something like &quot;hee hee&quot; in English. (I spell it &quot;hee hee&quot; and not &quot;he he&quot; so as not to confuse it with 呵呵.)</p>
<h1>嘿嘿</h1>
<p><em>Heihei</em> is a mischievous or cunning laugh and is used more by males. It can also be an honest laugh, though, too.</p>

<p>"呵呵" means something different in online chat.</p>

<p>At first, "呵呵" is as simple as "哈哈"，“嘿嘿” when I even used it a lot in online chat. </p>

<p>Then, "呵呵" become the best choice when you do not know how to reply to someone's message. So this is where things goes wrong about "呵呵". When someone keep talking to you, and you reply nothing meaningful but "呵呵", sooner or later, he or she become boring about the words.</p>

<p>At last, a picture changed everything. It show below:</p>

<p>Ever since the picture got famous on Internet, people stop using it as its usual meaning but means something different. Sometime it's a joke, sometime it is offensive.</p>

<p>By the way, "呵呵" was the top 1 of of "the most hurting words in online chat of 2014". Full list shows below:</p>

<p>1.呵呵</p>

<p>all of those are onomatopoeias</p>

<p>actually the meanings vary a lot if you speak a different dialect.</p>

<p>for example 嘻嘻 is /xixi/ in mandarin, /hihi/ in Minnan, /heihei/ in Cantonese.</p>

<p>if you are used to 嘻嘻 in mandarin and you read a comic book from hongkong, you'll wonder why those handsome masculine protagonists /xixi/ like a girl who falls in love the first time while actually the author means a cheeky /heihei/.</p>

<p>This is only one example, but if you look at the news papers or daily languages in regions of different dialects, the way they use onomatopoeias are fundamentally different.</p>
