The lyrics...

悟空太热了
WU KONG TAI RE LE
Monkey it's too hot

我受不了了
WO SHOU BU LIAO LE
I can't stand it

热死
RE SI
It's killing me

火焰山有八百里
HUO YEN SHAN YOU BA BAI LI
These mountains are covered with flames for over eight hundred miles

火势烈
HUO SHI LIE
The fire is severe

阿弥陀佛
O MI TO FU

我们怎样能度过此劫
WO MEN ZEN YANG NENG DU GUO ZI JIE
How can we possibly cross here

让行者去借宝扇
RANG XING ZHE QU JIE BAO SHAN
The magic palm-leaf fan from Princess Iron Fan is your only hope

把火扑灭
BA HUO PU MIE
To extinguish the fire
