Weather change

It was constantly between 25C and 30C back in Malaysia. Shanghai was 8C when I arrived. Luckily I brought my winter jacket back. Nevertheless, the change of weather still makes my nose and throat uneasy. Some says it is still consider a warm winter in Shanghai this year, but I really could not feel any 'warm'. I already using the air-conds in my apartment as a heater now. I have not got time to change my quilt to the thicker one for winter. It was a torture to get in and out from bed during winter, seriously.
