今日又再返工4日，星期五第六次化療，也是最後一次。昨天同中大一些同事打乒乓球，因為大家都不是球技高超，所以都不太劇烈。不過因為太耐無打波，今天覺得腰部有點兒累呢！

Today, back to office again.  The 6th (last) chemo will be taken coming Friday. After that and taking 2 week's rest, I will be back to office permanently.

Yesterday, I joined the table-tennis game with CU colleagues. Most of the players are not skillful so the game was not very exciting to me.  However, not doing exercise for months, I feel a little bit sore on the lumber region today.
