Where are we begin it ????

This hanjie makes no sense! There are only a few black squares that can be filled in to start and then there's no way of knowing what comes next. A hanjie is supposed to be logical with only one correct answer. Very disappointed with this one.

Hints please?

The puzzle is five stars altogether - one large star and four smaller stars.

To help you start I will give you the first ten rows. This will complete the top two smaller stars (one in the left hand corner and one in the right hand corner) and the top part of the bigger star.

R1 = C4, C13, C22
R2 and R3 = C3, C5, C12, C14, C21, C23
R4 = C1-2, C6-7, C11, C15, C19-20, C24-25
R5 = C2, C6, C11, C15, C20, C24
R6 = C3, C5, C10, C16, C21, C23
R7= C2, C4, C6, C10, C16, C20, C22, C24
R8 = C1-3, C5-7, C9, C12, C14, C17, C18-21, C23-25
R9= C9, C12, C14, C17
R10= C1-8, C11, C15, C18-25

I hope this helps.

For the remaining two smaller stars, one is inside the big star and the other is underneath the big star. Both have there top points in C13.

Many thanks to Puzzledanita. I have tried many shapes of the big star - but wouldn´t think of the small star inside and therefore couldn´t solve it.

Little stars are tricky but finally got there!

HINTS
R25 C2-5 and 20-24 are bottom "feet" of big star, R25 C10-12 and 14-16 are bottom "feet" of little star. This little star spans rows 21-25.

The little star in the centre of the big star spans rows 7-15, with feet at R15 C9-11 and 15-17.
