@chrisjiang even though i cant read chinese well and dont quite fully understand what you are saying , but Jolin is singing live and is singing her own songs. It is common for songs to have another version in another language anyway. Definately better than all in china.
for an asian artist what she's doing is definitely out of the oridinary since she's dancing and singing and not just singing about love. but compared to north american music she is way behind. jolin tsai is good for asian music, but compare her to singers here jolin tsai don't even hold a candle.
