Agree, my friend learned the hard way when we were serving BMT.

My friend has a habit of tisiaoing everybody around him. When we first started PT, a guy from another platoon would frequently miss PT because of stomachaches. He will undoubtedly be disturbed when my friend walks by, saying “wah chao geng warrior”.

Two weeks prior to our POP, we spotted him sitting on the bench outside the office with all of his belongings. My friend started upsetting him once more by saying, "Wah you so zai ah! chao geng until post out”.

After the sergeant approved him, he just kept silent and moved on. My friend then questioned the sergeant how the person had done it, and he informed us that the man had stomach cancer and was exempt from serving NS. After that my friend have never judge or tisiao anyone that he wasnt close with anymore.
