Solved
hi
i read this subject for custom coordinate systems
http://docs.locusmap.eu/doku.php?id=manual:advanced:customization:coord
there is EPSG code for Taiwan TM2 and i add it to config_projections.cfg
http://spatialreference.org/ref/?search=taiwan
1|3825|Penghu TM2(TWD97)|TWD97 TM2 zone 119|Taiwan
1|3826|Taiwan TM2(TWD97)|TWD97 TM2 zone 121|Taiwan
1|3827|Penghu TM2(TWD67)|TWD67 TM2 zone 119|Taiwan
1|3828|Taiwan TM2(TWD67)|TWD67 TM2 zone 121|Taiwan
i check the coords and location by this website (sorry it's only chinese)
http://www.sunriver.com.tw/taiwanmap/grid_tm2_convert.php

Good day Jing,
am I wrong or on your screenshots it looks correctly (on both of them) ?

'think the point should be on same place - on both screenshots
isn't it?

Hmm I'm worried I cannot help here.
This is internal configuration that Locus use for transformation
These parameters are used for Proj.4 library that is used in Locus. So if your web site is correct, and these Proj.4 parameters are also correct (for unknown reason they are not visible on web http://spatialreference.org/ref/epsg/3828/ - tap on proj.4) , then issue should be in Proj.4 library in Locus only.
Because Locus use older version of this lib, solution should be update to new version and if this helps, report to it's developers. Unfortunately update is not currently possible.
