Two weeks ago Facebook's Mark Zuckerberg posted a video of himself doing a speech and Q-and-A session in China, in Chinese. Soon thereafter, Isaac Stone Fish of Foreign Policy, whose friends had asked him how Zuckerberg's Chinese was, responded "terrible." He did an item called "Mark Zuckerberg Speaks Chinese Like a Seven-Year-Old." Yesterday I posted a critical-review-of-that-critical-review, by Kevin Slaten, plus some other thoughts about language learning.

Since then I've received an avalanche of interesting letters, and I plan to share an assortment of them tomorrow. For now, Isaac Stone Fish deserves a clear shot to reply to Kevin Slaten's criticisms. I turn the floor over to him:

Thanks Mr. Fallows for your thoughtful post, and for giving me the chance to respond, and Mr. Slaten, thanks for your contribution.

After Zuckerberg spoke Mandarin, several news outlets claimed his Mandarin was fluent. That is incorrect. There’s a difference between speaking unstandard Mandarin -- which, as Mr. Slaten correctly pointed out, is what that Mao and Deng spoke -- and speaking broken Mandarin with mangled tones, which is the way Zuckerberg spoke.

The problem with Zuckerberg’s Mandarin was not just his pronunciation; he also made many grammatical errors. You’re right that a seven-year-old native speaker -- even if his mouth was full of marbles -- would not make the tonal or grammatical errors that Zuckerberg made. It was the best analogy I could think of to describe the quality of his Mandarin: any other suggestions for analogies would be much appreciated.

Learning Chinese was great fun, and very helpful to me in my career; I strongly recommend it to people who want to work in China. But it’s very time-consuming. Even if it would be encouraging, I am not going to pretend that a beginner can study Chinese part-time for a few years and suddenly learn to speak excellent Mandarin.

In the end of his piece, Mr. Slaten writes, “Speaking of Chinese fluency, Mr. Stone Fish, we didn't catch that link to your own 30-minute Chinese-language speech in front of millions of people around the world.”

I must admit defeat. Yes, I could give a 30-minute Chinese-language speech much better than Zuckerberg’s, especially if I prepared for the topic, as Zuckerberg seemed to have done. But I will never be able to satisfy Mr. Slaten’s request to do so in front of millions of people. Why? Because only an exceedingly small number of people actually care about the level of my Mandarin. Take my former Chinese teachers and my parents out of that equation, and that number drops dangerously close to zero.

Thanks to Isaac Stone Fish for his good-humored response, to Kevin Slaten for his stimulus for this discussion, and to everyone else who has written. Tomorrow it will be your turn.
