Today I asked at the Hamilu DMV and nobody knew, if or when a translation of the second test is coming. But I spoke to the beautiful Jane Shao at Yiqi Motorcycle Co. next to the DMV and she confirmed that it is only 800 questions, multiple choice, one correct answer. If you know a bit Chinese, you can try to memorize the correct answers. At least, that is a 100% legal way and it's probably cheaper than the agent (if that matters).
Btw, Jane also said, that besides Junti there would be only Jinqiu offering (3-wheel-)motorcycle classes. But as I already called them, I can confirm that it is still only Junti. Jinqiu discontinued the classes.
