You are referring to the Immense Tyrant Without Compare

Here's the problem with Mandarin: move an inch outside your speciality, and there is no guarantee that any of the words will mean anything to you. I had been speaking Chinese for twenty years, and was in town to give a lecture on medieval history, but the strange sigils describing arcane translation nightmares, like McFlurry and McNugget, might as well have been Martian.

...

'What's that thing called,' I began wearily, 'which is very big probably the biggest thing that you have, and there are two all-beef patties, special sauce, lettuce, cheese, pickles and onions, all in a sesame seed bun?'

'Ah,' said the bespectacled youth before me, 'you are referring to the Immense Tyrant Without Compare (ju wu ba).'

At last, a new use for the archaic term for a Bronze Age overlord, now recognised by twenty-first-century Chinese teenagers as the word for a Big Mac.

'He was lying,' Deng replied

Deng found himself sitting next to Shirley MacLaine ... She was fulsome in praise for some of the benefits of Mao's policies, and told Deng of a story she had heard about a Chinese intellectual who was actually grateful for the Cultural Revolution. Sent into the countryside to grow tomatoes, she said, the man said he had experienced a wonderful object lesson in realism in realism and human life.

'He was lying,' Deng replied.

There is no subjunctive perfect in Chinese

There was something of a tussle within the family over who would translate Dr Chao's prose into English. Her daughter did much of the work, only for Chao's linguist husband to step in and pepper the account with hectoring qualifications - 'There is no subjunctive perfect in Chinese,' he harrumphs, in an entirely unnecessary footnote to a paragraph about what to say when someone serves you Shark's Fin Soup. But at the end of the family feuding a firm text remained, often in quaintly off-kilter English, and with a few translation decisions that would endure.

Soybeans have higher nutrient values than millet, but a lower rate of digestion

The Zhou people's tendency to boil everything would not be all that helpful with soybeans, and would lead to tasteless sludge. Soybeans have higher nutrient values than millet, but a lower rate of digestion, at 22 per cent if they are merely boiled, but rising to 65 per cent with fermentation. In other words, they can only come into their own with the introduction of more advanced technology for cooking and preparation. When they do, they offer the best yield per acre of protein, compared to the same land used for rearing milk, eggs, or meat.
