Are iTalki tutors in China unavailable over Chinese New Year? If they take a holiday, how long would they usually take?
Does that mean iTalki challengers learning Mandarin might not finish the challenge? :-)
If they have prearranged the classes with the teachers, they might still finish the challenge. Not sure if that might be against the rule or not (I am not participating in the challenge).
If they have selected Mandarin tutors/teachers (living outside of China) who don't take Chinese New Year break, then the holiday break won't affect them.
Hope that helps :)
Some have even more time to study and teach languages.
The China lunar new year is a biggest holiday in China. It will start from Feb. 18th to 24th. this year. That is what I know. I have no idea about your other questions.
