Work wise, it really depends.

Life wise, pretty fun. Cuz from Guangzhou, you can visit many surrounding places.
I visit Hong Kong and Macau on alternative months.
During the weekends, I go up the Baiyun Mountain and bicycling at Dafu Mountain.
If I have longer holidays, I go to other provinces like Chongqing and Hangzhou just to see what its like there.
Shopping? Everything can be bought on Taobao at a fraction of the price sold in Malaysia. Everyday you get parcels which is super exciting.
Food? Macam macam ada. If you miss Malaysian food, there are many Malaysian restaurants opened by Malaysians.
Not to mention, there's 4 seasons here. So you get to experience winter too. Winter is not very cold so that's also a good thing.
Very interesting lifestyle. Been here for so long and the main reason why I am not going back is cuz I like visiting.
