The Words of the Day for today is谢谢， xiè xie (thank you). Contrary to 你好,nǐ hǎo (hello), probably the most spoken Mandarin words, 谢谢 seems to be well known, but not as widely spoken. It might be because it's very hard to pronounce. The "X" in English mostly make the sound of "ks", but in Chinese, it sounds like "s", which can be quite confusing. Hope this blogs helps.
