For my wife, the key was having her find friends of her own.  Thankfully, I have several friends with Chinese wives and I introduced her to them.  Then, there was the trips to the Chinese supermarket in town.  That always made her happy.

The biggest thing is what expats need to do in order to survive.  She needs to go out and get a life that is beyond you and the kids.  That will help tremendously.

On top of that, you can get a VPN that allows you to connect to HK so she can connect up to the Chinese websites that broadcast all of the Chinese shows.

I agree with xpat -Iohn,making friends with other Chinese,where you live.Try websites or even University as a start.i bet some students would be very greatful for a Chinese friend or even mother figure

I was homesick When I was in Australia,I missed everything about China,especially my family and the food.I feel like,I just wanted to buy a ticket ,then leave,But It's not the thing I really wanted to do,I don't want to see my husband and his family unhappy because of me.

So,I talked to my family and my friends a lot by using skype,It's damn cheap.

 and I went to China town a lot ,I talked to people there in Chinese,I ate  the food there and bought some food back for me to cook.It really helped  me.

Keeping yourself busy is a good way to get rid of your home sickness.

We are the free spirits who have decided to come to China (And maybe alot of people by choice). So we have a different thinking to the average person who has lived in their own country all their life. Its hard to have compassion, I think a lot of people who come here if they want their other half (Chinese) to be happy you may have to seriously consider staying here, even if they say its ok to move abroad.

If the other person is not happy in a relationship, its going to directly affect YOU.

I cook the traditional dishes from his country

Just Drink Drink and Drink...after one botlle..everyone will forget everything..

My wife's mother was against her coming home with me, so I just bought her a laptop with a webcam and setup QQ on it. She now gets to talk to her mother face-to-face every day. Although it isn't the same as talking to her in person, it's much better than nothing, and far better -- and less expensive! -- than using a telephone.

Moreover, since there are a lot of Chinese people in my hometown, and I already made friends with a lot of them, I introduced her to some of them.

       Ha,ha,ha... "homesick ", I think all peoples who lives abroad have in same degree. 

Get mature!!!   

After my wife and I got married we lived in UK for 6 years, before coming back to China.

I encouraged my wife to make Chinese friends but that didn't work as she is too introverted, so I encouraged her to go to English classes, which helped, as at least she was mixing with other 'foreigners' even if they weren't Chinese and of course it helped with her Citizenship application later.

The big breakthroughs though, were discovering some Chinese supermarkets (Wing Yip and a couple of others), which meant she could get Chinese vegetables, (believe it or not it was the veggies she missed most) and an 0800 number that enabled you to call China from the UK for 1p a minute on weekdays and 2p per minute on weekends. It also meant I couldn't use the phone for 7 or 8 hours per day, but at least we had mobiles!
