If u just listen but not practice at all, you must not be good in speaking Putonghua~

Ofcoz, u hv to pursue further education becoz learning language has no ending, u can find new things to learn even u're an expert of it
All in all, practice makes perfect, +oil!

那要看你的學習態度和天份, 只要有心, 認真聽, 多請教, 不怕剛開始人家笑你講得不準, 多練習. 加上如果你天份好, 發音準, 三個月至半年就能掌握了. 如果你具備了上面的努力, 只差天份不夠好, 發音不太準, 那你練習的時間可能就要拉長一倍以上. 但如你根本無心學, 聽完就忘到一邊了, 那是再長的時間都很難學好的.
努力！加油！！
