So far everything is very normal. The crying when you leave her will get better eventually as she becomes sure you are coming back. Chi's don't like being separated from their chosen person at all.
The biting thing is also normal and it's something nearly all of us have had to break our chi's from doing. One thing you can try is telling her no and immediately putting her down on the floor and ignoring her for a while every time she bites. With many chi's that works. It didn't work with Marcus and when he hadn't gotten any better by 10 weeks (I brought him home at 8 weeks) I told him No firmly and spatted him with an empty envelope. It certainly didn't hurt him but it scared and surprised him and made him think.
