The screenshot of the Font tab of the "Title" style in the first slide of the
Progress template

Tested in Daily build (2017-12-28_10.01.02) and Chinese (traditional) locale
(zh-tw).

The default templates of Impress provide poor default Asian fonts settings. 
Let's take the "Progress" template for example.

How reproducible: always
Reproduce Steps:
1. Install Daily Build and set the locale to Chinese (traditional) in Tools >
Options > Language Settings > Language > Language Of "Locale setting" to
"Chinese (traditional)" and enable Default Languages for Documents "Asain:"
checkbox then seclect "Chinese (traditional)"
2. Press OK and restart
3. Open Impress and select any of the default templates, such as "Progress" for
example here.

Actual Result of the styles in the first slide of the Progress template:
In the Font tab of the "Title" style:
    Western Text Font
    Family: Liberation Sans    Style: Bold    Size: 75

    Asian Text Font
    Family: 思源宋體    Style: Regular    Size: 24

In the Font tab of the "Outline 1" style:
    Western Text Font
    Family: Liberation Sans    Style: Regular    Size: 36

    Asian Text Font
    Family: 思源宋體    Style: Regular    Size: 24

Expected result:
1. Sans-serif font families should mapped to any 黑體/方體/ゴシック (Hei/Fung/Gothic
typeface). In the case of zh-tw locale, it should map to the CJK_HEADING of
zh-tw locale defined in VCL.xcu.
2. Serif font families should map to any 明體/宋體/明朝體 (Ming/Sung/Mincho typeface).
 In the case of zh-tw locale, it should map to the CJK_TEXT of zh-tw locale
defined in VCL.xcu.
3. The Asian Text Font "Style" and "Size" should be in coherent with Western
Text Font Style and Size. If it is Bold and 75 points for Western Text, it is
better to be the same for Asian Text. 

Bottom line:
Mostly all the templates have the problems on Asian Text Font Family, Style and
Size. It is best to have a corresponding setting for each locale. If that
cannot be done, just use the same generic font family (matchmaking for Sans and
Serif fonts), the same style (Regular, Bold, etc.), and the same size.

PS. here is a brief view of the first candidate CJK font of zh-tw locale in
VCL.xcu:
CJK_HEADING: 思源黑體 (Source Han Sans)
CJK_TEXT: 思源宋體 (Source Han Serif)
CJK_PRESENTATION: 思源黑體 (Source Han Sans)
CJK_SPREADSHEET: 思源黑體 (Source Han Sans)
