Thanks for the tool.co.uk link, Harmonicamoon.
Though not intending to take up Mayan language, I will "mine" the site for some Mayan words to be used in a little project I have in mind.
(I had better hurry, it seems ~ as the Last Days are nearly here!
On the question of Mandarin Chinese, I was staying in a Shanghai hotel five years ago, and caught a bit of the local television programs. All were in Chinese (and quite beyond me) but I chanced to hit upon a daily short [5-10 minute] session which instructed English-speakers on Mandarin word usage.
This was aimed at Americans apparently . . . judging by the English accent used by the [Western] instructor. But I didn't stay long enough to really benefit much . . . they were explaining about 3 words per session . . . and I think it might have taken me a while to clock up the 2,000 hours of instruction which allegedly gives fluency. I daresay real immersion is necessary.
There are indeed signs-of-the-times that China is changing.
At least in the central city, large brand / product-line advertisements were everywhere ~ and quite usually featuring Western female models (all young and beautiful . . . what a surprise, that!).
And the TV advertisements ~ there is something rather familiar about them.
While seeing a bit of some Historical Drama of the 1930's or maybe 40's and featuring actors with unmistakeable resemblences to Mao, Chou-En-Lai, and so on . . . there was one emotional scene where General Chiang-Kai-Shek stands up to address a group of his officers. The General gave an impassioned speech [alas, the topic unguessable to me] and at the end, flung up his arm in a fierce gesture. Cut to Kentucky Fried Chicken advertisement.
