I go in twice liao.
You can go in by end of Jurong park which a back door leads all the
way to main area of Tang dynasty.
Or u can try the extreme left of the main gate which there are many
cut holes of the fences.
The most fantastic part abt the abandon Tang dynasy is the six
storey pagoda which is fcuking breezely in the afternoon. Can see
the whole Jurong view. Nice! I brought my ger to there but no do
that thing. Haha...
