YI SHIBi Token

Ownable._root (#92) is never initialized. It is used in:
YISHIBi._tFeeTotal (#247) is never initialized. It is used in:
- YISHIBi.totalFees() (#411-413)
YISHIBi.simuAddres (#267) is never initialized. It is used in:
- YISHIBi.withDrawToken() (#323-336)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

Contract ticker (YI SHIBi) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

YISHIBi._rOwnedInit(address,uint256) (#298-301) performs a multiplication on the result of a division:
-_rOwned[account] = _rTotal.div(100).mul(rate) (#299)
YISHIBi._rOwnedInit(address,uint256) (#298-301) performs a multiplication on the result of a division:
-Transfer(address(0),account,_tTotal.div(100).mul(rate)) (#300)
YISHIBi.withDrawToken() (#323-336) performs a multiplication on the result of a division:
-mouthNum = (block.timestamp.sub(swapStart)).div(2592000) (#329)
-_transfer(address(this),simuAddres,amount.mul(mouthNum).div(12)) (#334)
YISHIBi._tokenTransfer(address,address,uint256,bool) (#490-543) performs a multiplication on the result of a division:
-_takeTransfer(sender,fundAddress,tAmount.div(100).mul(4),currentRate) (#513-518)
YISHIBi._tokenTransfer(address,address,uint256,bool) (#490-543) performs a multiplication on the result of a division:
-_takeTransfer(sender,charityAddress,tAmount.div(100).mul(1),currentRate) (#520-525)
YISHIBi._tokenTransfer(address,address,uint256,bool) (#490-543) performs a multiplication on the result of a division:
-_rOwned[recipient] = _rOwned[recipient].add(rAmount.div(100).mul(recipientRate)) (#539-541)
YISHIBi._tokenTransfer(address,address,uint256,bool) (#490-543) performs a multiplication on the result of a division:
-_takeTransfer(sender,_destroyAddress,tAmount.div(100).mul(5),currentRate) (#527-532)
YISHIBi._tokenTransfer(address,address,uint256,bool) (#490-543) performs a multiplication on the result of a division:
-Transfer(sender,recipient,tAmount.div(100).mul(recipientRate)) (#542)
Consider ordering multiplication before division.

YISHIBi._tokenTransfer(address,address,uint256,bool).rate (#502) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

YISHIBi.allowance(address,address).owner (#347) shadows:
- Ownable.owner() (#97-99) (function)
YISHIBi._approve(address,address,uint256).owner (#461) shadows:
- Ownable.owner() (#97-99) (function)
Rename the local variables that shadow another component.

Ownable.changeOwner(address) (#109-111) should emit an event for:
- _owner = newOwner (#110)
Emit an event for critical parameter changes.

Ownable.changeOwner(address).newOwner (#109) lacks a zero-check on :
- _owner = newOwner (#110)
YISHIBi.changeRouter(address).router (#556) lacks a zero-check on :
- uniswapV2Pair = router (#557)
Check that the address is not zero.

YISHIBi.withDrawToken() (#323-336) uses timestamp for comparisons
Dangerous comparisons:
- require(bool)(mouthNum > 0) (#330)
- mouthNum > 12 (#331)
YISHIBi.tokenFromReflection(uint256) (#415-426) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(rAmount <= _rTotal,Amount must be less than total reflections) (#420-423)
YISHIBi._transfer(address,address,uint256) (#472-487) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(amount > 0,Transfer amount must be greater than zero) (#479)
- _isExcludedFromFee[from] || _isExcludedFromFee[to] || destroyAmount >= 88000000000 * (10 ** 8) (#483)
Avoid relying on block.timestamp.
