        如果问学中文普通话的朋友：哪一部分最难？相信很多人都会说：“声调，四个声调。” 我经常对学生说：“说中文普通话就像唱歌一样，其实不难。” 或许有人会说：你这是：“站着说话不腰疼”，我要说的是：如果您把最困难的“四声”问题解决好了，说好普通话其实还是一件挺愉快的事情。

        这个现象挺有意思的：同样是说中文，对待同样的事情，说出来的话可以是很不一样的，这可能就是成语和俗语的区别吧。同时，读书人和不读书人、社会地位高和低的人，在说中文时也是能让人听出来几分的哟。This phenomenon is very interesting: Regarding speak Chinese, the same thing to say the words can be very different, which may be the difference between idioms and colloquial.  At the same time, Knowledgeable people and non- Knowledgeable people, and people of high and low social status can also be recognized when speaking Chinese.

       找人帮忙的时候，一定要找那个真正有能力、能帮到点子上的人。就像我们学语言，每个学习者都像孙悟空一样，在这个特定的圈子里，施展着各种本事折腾过一阵子了，但是总有些难点、顽疾，就像悟空遇到的各类妖怪，打不掉也躲不过，这时候就要请菩萨帮忙了。有经验的老师就是这样的人。When looking for help, always look for someone who is really competent and can help with ideas. Just like our language learning, each learner is like Sun Wukong, who has been struggling with various skills for a while in this particular circle. However, there are always some difficulties and intractable diseases, just like all kinds of demons that The Monkey can't get rid of or avoid. At this time, we need to ask the Bodhisattva for help.  Experienced teachers are such people.
