你好！我有一個問題：我怎麼能得到黃的腰帶？I’m new and really want to learn Chinese. I took and passed the test and it said I was Yellow belt now but when I checked my profile, it said I was still a White belt.

Also, I know that the intonation of the word 不 changes according to the intonation of the word after it. Are there any other such irregularities concerning intonation? On the video to the experience “Title : Usages of Where – Where will, Where are, Where is, Where did (2007-03-22)”, it shows the 明 of 明天 to be the first tone while everywhere else I see it being written as second tone. Is there a mistake somewhere? 多謝 in advance for your support.
