2 lines are drawn at the left top right hand corner of a cheque means this is a crossed cheque. You cannot cash a crossed cheque and could only be paid to a person account for bank clearing.
There are 2 types of crossing (1) general (2) specific.
A general crossing means lines are there but without the crossing out of the words 'or bearer' after the name of the payee. In this case, this cheque could be paid in to any person's bank account for clearing.
A specific crossing means there are 'Account Payee Only' in between the 2 lines. In this case, cheque could ONLY be paid in to that named person ( Payee )'s bank account for clearing. The wordings ' or bearer ' is crossed out.

在支票中間或左上角有劃兩條直線, 就係劃線支票, 你可以下次申請支票薄時選擇己預設有劃線的支票薄

支票左上角劃上兩條直線，或者蓋上「account payee only」印章，將支票「交付來人」勾劃，並寫上收款人名稱，這就是一張劃線支票。
