Any help would greatly be appreciated - using symmetry I can guess most of it but I'm left with a lot of '1's at the end and no idea.
I'm normally a very patient person and give people the benefit of being a beginner and newbie when creating puzzles like this, espically as my earlier puzzles were terrible.
However, I find myself getting annoyed with you Saeed, which I really don't want to be. On several of your puzzles it is complete and utter guess work and only with hints/help from others can it be completed. People have politely asked if you could try your Hanjie before posting in order to stop this, yet it appears you are not listening to this advice and continue to make puzzles like this one, which are not enjoyable.
I'm sorry in advance if I have offended anyone with my posting but I felt the need on this case to say something.
Corners are filled, The 5 in r10 starts in c6. And the 2 in r8 in c9. Join the 2s in the corners to the 2s in the centre with parallel lines. Should help a bit.
Thanks Teesea and Joe Tramp - I had got that far already it was after this part that I struggled but soon realised by re-looking at it that the ones made a triangle coming off the centre lines. This then solved the puzzle.
