Miss wong understands (the - her) problem very well-she is 1.6 metres and weighs
77 kilograms. "My two sisters and (me - I) are fat.My (eldel - eldest) sister weighs more (than) 90 kg. For Chinese this is a bit heavy really," she said.
Before I (open - opened) this shop we always had trouble (in) looking for dresses in
the right size. We were forced (to) wear T-shirts and jeans (that are - designed) for western people. They are terribly big and we (are - no are) really dislike them.

Miss Wong understands her problem very well - she is 1.6 meters tall and weighing 77 kilograms. "My two sisters and I are fat. My eldest sister weighs more than 90kg. As for Chinese, it's really a bit heavy,"she said.
Before I opened this shop, we always had trouble in looking for dresses of our size. We were forced to wear T-shirts and jeans designed for western people which are so big and we dislike them very much.
