Hello? I'm Korean E.L.F.大家好，
I'm sorry that I'm not good at English and Chinese.
I heared you will buy SJ's 4th album [BONAMANA].
So I suggest you buy at the place which apply 4th album's volume of sales to Hanteo Chart. (http://www.hanteo.com/)
我聽說你們將要買SJ的四輯 《美人啊》，所以我建議你們在可以計入HANTEO chart四輯銷量的地方購買。
Shops which apply 4th album's volume of sales to Hanteo Chart
: Interpark, Yes24, KyoBo, LessMusic, Hottracks etc.
可以提供專輯銷量給hanteo chart的商店有：Interpark, Yes24, KyoBo, LessMusic, Hottracks等等
And when you buy SJ's 4th album, you should require receipt at each album.What I saying is 1 cd = 1 receipt, 2 cd = 2 receipt. Not 100000 cd = 1 receipt. It's important because if you buy 10000 cd with 1 receipt, that will apply at 1 cd. But if you buy 10000cd with 10000 receipt, that will apply at 10000 cd.
所以，當你們買SJ的四輯時，每張專輯都應該要一張小票（收據）。一張專輯要一張小票，2張專輯要兩張小票。 不是100000張專輯只要一張小票。這很重要，因為如果你 買10000張專輯只要一張小票的話，只相當於計入的銷量為1.但是如果你賣10000張專輯帶10000張小票的話，銷量記為10000張專輯。
