thanks Johnny, 'the engineer' of KLNBJJ. He has fixed a lot of broken parts of the gym.. this time he installed metal frames on our windows.

We have a lot of small kids, so we had kept our windows closed. now we can get fresh air in from outside!
謝謝九龍柔術工程師 Johnny。在練習場上他幫忙修理好部份的損壞，這一次他安裝了金屬窗花。
我們這裡有很多小孩子練習，所以一直都關上了窗。現在我們可以呼吸新鮮空氣了 !
