What is the weather thickness in April in Guangxi?

In April, I usually cover myself with a 4 kg quilt. 4 kg quilt is suitable for spring and autumn quilts, and it is used at about 10 degrees Celsius. In fact, 4 kg quilt refers to 4 kg filler, plus cover and quilt cover, which is about 5 kg. So the cover of April spring clothes is just right. For example, there is central heating in most places in the north, so the indoor temperature will not be very low. The thickness should be determined according to the room temperature: 1, room temperature 10 degrees, single quilt about 6 kg, double quilt 8- 10 kg. 2, the room temperature is about 15 degrees, the single quilt is about 4-5 kilograms, and the double quilt is 6-7 kilograms. 3, the room temperature is greater than 20 degrees, about 2 kg -3 kg for a single person and 3-4 kg for a double person.
