ordinary people to make their homes on the equator (道), although often they may
feel uncomfortably hot there. Millions do it. But as for the North Pole (北极)——we

in ships for thousands of years; but only a few men, with great difficulty and
in very recent time, have ever crossed the ice to the North Pole. {{/U}}So it may
