Hi, I would like to ask regarding weather and suitable cloth on end of March in Guangzhou

I've lived in the city for about three years. During March 25-29, although it would be fine, it is still a little cool for us from Malaysia. Its lowest temperature is about 12C and the highest temperatire would be around 25C to my experience. Therefore, I suggest you take along light sweater, jacket and jeans as well as a long-sleeved shirt for sudden hot afternoon.
