How happy it is to have friends from far away!

Fortunately, the Chinese know how hard their language is – which is why efforts like Zuckerberg’s are applauded. I have lost count of the number of times that my dismal Chinese has been praised and complimented, by everyone from taxi drivers to government officials.

After decades (or in the Chinese mind, centuries) of arrogant foreigners arriving in China and not bothering to learn the language, it is a mark of respect to have a go.

Sadly, as you make progress, the novelty wears off. After seven years here, those who once praised and encouraged me now chide me for getting a tone wrong. I suppose it is a sign of progress to be corrected, rather than simply to win patronising praise, but I miss the old days.

The foolish old man who moved the mountains

There is a Chinese folk tale that sums up the effort required to struggle with Mandarin. A man in his nineties began picking up stones in order to level two huge mountains. When told he was an idiot, given the scale of the task and the time he had left, he simply said: “Certainly I cannot do it. But when I die, there will be my children to carry on the work, and the children will have grandchildren, and the grandchildren will again have children. So my children and grandchildren are endless, while the mountains cannot grow bigger in size. Why can’t they be levelled some day?”

You cannot catch a cub without venturing to the tiger’s den

For British schoolchildren, there is no short cut. The popular “Chineasy” pictogram cards are charming, but not a magic bullet. You may learn to recognise a few Chinese pictograms, but they do not teach pronunciation and the sea of non-pictographic characters stretches to the horizon.

The best way to shorten the slog is the most straightforward. While children will not pick up much Mandarin in English classrooms, it may open their minds to visit China. And here, if they can find a place to immerse themselves, they have a good chance of learning the language.
