The shipping date has been delayed several times.

船期一拖再拖。

Did you understand every word? Let's hear it again. " This e-mail is to keep you informed about the shipping date" .

你听懂每个单词了吗？我们再听一遍。" This e-mail is to keep you informed about the shipping date" 。

I'm not going to ask you to pay attention to which country is harvesting when or understand shipping dates or that kind of stuff but do look to buy from places where the offering changes reasonably regularly.

我不会要求您注意哪个国家/地区在何时收获或了解运输日期或类似的东西，但确实希望从产品定期合理变化的地方购买。
